The 108-mantra-per-graha apparatus is the wall. Nine doors, 108 keys each, 972 mantras total. The problem the practitioner faces is operational: which key for me, today, given this chart and this moment. Foss inherits from Pandit Sanjay Rath a four-method selection procedure, originally — Rath told Foss — "closely kept by a few Indian Astrologers" before its release in Yoga of the Planets. The four methods are not interchangeable; each gives a different cut at the chart, and each cut answers a different question. Pick the method that matches what you are asking for.
Pick a number between 1 and 108 by any non-deliberate procedure. Open a book three times, take the final digit of each page number (e.g., pages 21, 143, 79 → 1, 3, 9 → 139, subtract 108 to land in range → 31). Or use Foss's Shri Jyoti Star software, which generates a random number in the 1-108 range on demand. Or ask another person for a number — if they give you a number above 108, subtract 108 until you land in range.
When this method works: when you don't have astrological data, when you want to bypass intellectual selection entirely, when a client or student is sitting with you and the situation calls for a quick draw, when "nature is talking and you are quiet enough to listen." Foss is explicit that random-draw is not arbitrary — it is the Vedic prashna (horary) principle in compressed form: the answer arrives because the question was asked under specific conditions of attentive stillness. The mechanism is selection-by-resonance, not selection-by-chance.
Use the sign-degree table below. Find your planet's sidereal position (e.g., from Shri Jyoti Star or any Vedic astrology software). Look up the row for the sign and the column for the degree. The number in the intersection is your mantra number for that planet.

Worked example. Sun at Virgo 5° → row Virgo, column 6°40' (because 5° falls between 3°20' and 6°40') → number 47. The 47th name of the Sun is om śāntāya namaḥ (Sūrya 47, "salutations to the peaceful one"). That is the mantra for your Sun, counted from the start of the zodiac.
Why "God's view." The count begins from the start of Aries (the start of the zodiac), which is — in Foss's framing — the view from the Creator's perspective. It is the most powerful of the four counts because it locates your planet on the universal map, not on a personal-relative map. Foss recommends starting practice with God's-view mantras and adding the other views as your practice matures.
The same table is used, but you change the starting-point.
Count from the Moon (social/personal view). Find the Moon's mantra-number using the table; find the planet-in-question's mantra-number using the table; subtract the Moon's from the planet's; add 1. If negative, add 108. The result is the planet's mantra-number from the Moon's perspective. Foss's worked example: Moon at Leo 8°10' → number 39. Sun at Sagittarius 4°30' → number 74. 74 − 39 + 1 = 36. The 36th name of the Sun is the mantra for your Sun-from-Moon — what the Sun looks like through the lens of your personal-social experience.
Count from the Sun (soul view). Same procedure, starting from the Sun's mantra-number. This gives the view of a planet from the perspective of your soul — what that planet means for your atman's trajectory rather than your social-personal experience.
Count from the Ascendant (body/health view). Same procedure, starting from the Ascendant's mantra-number. This gives the view of a planet from the perspective of your body and health — what that planet means for the physical vehicle in this life.
Each view answers a different question:
The fourfold counting also applies to Vimshottari Dashā cycles. If you are in a Jupiter major-period with a Sun sub-period (a bhukti), count from Jupiter's mantra-number to the Sun's mantra-number and use the resulting number from the Sun's mantra list. This gives you the mantra specific to your current bhukti — the most operationally-immediate mantra for the karmic phase you are presently moving through. Foss does not recommend this as a beginner's practice but notes it as the most advanced application of the counting system.
Evidence: The four-method system as described is Foss's faithful transmission of what Sanjay Rath transmitted to him. The Shrīpati / Sripati-related table-construction is consistent with classical Indian astrological tables. The mathematical structure (subtract-and-add-1 with modulo-108) is straightforward.
Batch-2 interaction with the caveat-architecture. The four-method personal-mantra-selection works straightforwardly for benefic-graha mantras (Jupiter, Sun, Moon, Mercury, Venus) where the selected mantra can be chanted safely. For malefic-outer-planet selections (Saturn, Rāhu, Ketu) the selection-result requires special handling per Foss's caveat-architecture: "I do not recommend using the more challenging names as regular practice mantras and I certainly do not recommend you ask another person to do them even if they come up when you do the calculations described in the next chapter." (Foss intro, repeated in all 9 volumes.) This means: a personal-mantra-selection that lands on Saturn S34 / S88 / S102 / S105, Rāhu R3 / R23 / R66 / R85, or Ketu K57-and-cluster requires contemplation-mode rather than chanting-mode. The selection-system delivers the which mantra; the caveat-architecture delivers the how to engage with it. A practitioner using the selection-system for a personally-relevant malefic graha needs to know both architectures to operate the practice correctly. Foss embeds this knowledge in the intro of each volume so the selection-procedure is not divorced from the caveat-context.
Tensions: Foss is silent on what happens if a planet falls exactly on a boundary degree (e.g., Sun at exactly 6°40' Virgo). In practice, software handles boundary cases by rounding, but the manual procedure does not specify. Hold as operational ambiguity for novice practitioners; experienced practitioners handle this by consulting the chart's other indicators.
Open Questions: Are the four views (God / Moon / Sun / Ascendant) hierarchical (God-view dominant, others subordinate) or complementary (each answering a question the others cannot)? Foss leans toward complementary but recommends God-view first — this could be a teaching-sequence choice (start with the strongest) or a metaphysical claim (universal-karmic before personal-relational). The vault holds the question open.
The mechanism that makes this system reach outside Vedic astrology is the same data interpreted from multiple viewpoint-positions produces different operational guidance, and the interpretive-position is itself part of the data. That pattern shows up in several places where you might not expect it.
Behavioral mechanics / interview methodology: the Evans-style diagnostic question in interrogation and journalistic-interviewing structures the same person's testimony from multiple framing-positions — what-you-experienced, what-others-said-happened, what-you-think-happened. Each framing pulls out different content the witness has access to. The structural parallel: one underlying reality + multiple framing-perspectives = richer operational picture than any single perspective gives. The insight: Foss's four counts are not redundant — they are the prashna-equivalent of multi-frame elicitation, getting the same chart to speak from four positions because each position has access to a different layer of the karmic information. This reframes "you should consult an astrologer" as "you should have someone help you elicit your chart from multiple positions" — the technical lookup is secondary to the framing-multiplicity.
Creative practice / writing methodology: the writer's intuition-cluster (Bilton's Tetris-database + Macfarlane's river-intuition + Whyte's body-listening) all operate on a similar principle: the same material elicits different work depending on which intuition-channel you consult. The structural parallel: the practitioner's selection-procedure for which voice to write from is itself a craft-skill. The difference: writing-craft makes the selection-procedure tacit and slow-to-acquire (years of "finding your voice"); Foss makes it explicit and procedural (here are four counts, here is when to use each). The insight: explicit selection-procedures may compress what would otherwise be years of intuition-development — Foss's four-method system is the Sanjay-Rath-Achyutānanda lineage's compressed transmission of what other traditions leave to tacit apprenticeship. Adopting the explicit-procedure approach for the writing-craft tradition would mean naming, for each piece, which of your intuition-channels you are consulting and why before drafting begins.
Cross-domain / business: the LLM-as-standardization-pressure question asks what happens to human selection-skill when an algorithmic suggestion-engine starts making the selection for you. The structural parallel: a chart-reading software that auto-displays mantra-numbers (as Shri Jyoti Star does) automates what was previously a hand-calculation requiring the practitioner's engaged attention. The difference: the lookup is mechanical (no meaning-judgment); the interpretive-position selection (God-view vs Moon-view vs Sun-view vs Ascendant-view) remains the human's choice. The insight: some craft-elements are losable to automation without harm (the lookup) and some are losable only at cost (the interpretive-position selection) — knowing the difference is itself the contemporary craft-skill, and Foss's system gives a clean test-case: anything below the four-count-selection level is automatable; the selection-of-which-count remains the practitioner's contribution.
The Sharpest Implication: The four-method system treats the chart as a multi-perspectival object — there is no single "true" reading; there is a set of operationally-distinct readings indexed to which perspective you are taking. The reader who accepts this must reconsider any single-perspective practice in their life: which morning routine view, which work-decision lens, which relationship-frame are they defaulting to without realising they are choosing only one of several available counts? The mantra-system explicitly trains the practitioner to hold multiple counts simultaneously and use the count that matches the situation. The implied life-skill, transferred outside Vedic astrology: deliberate multi-framing as practice, not as occasional cognitive exercise.
