Sankhya Shastra (Vedic Numerology)

Sankhya Shastra ("science of numbers" in Sanskrit) is the numerological branch of the Vedic tradition, closely related to Jyotish (#18). Unlike Western numerological systems, it is organically embedded in the broader Vedic metaphysics: numbers here are not self-sufficient archetypes but expressions of the qualities of the planetary grahas that govern the entire Vedic worldview. The system is described in classical texts and survives to the present day in the practice of Indian numerologists.

Nine numbers correspond to nine grahas: 1 — Surya (Sun), 2 — Chandra (Moon), 3 — Guru (Jupiter), 4 — Rahu (North Lunar Node), 5 — Budha (Mercury), 6 — Shukra (Venus), 7 — Ketu (South Lunar Node), 8 — Shani (Saturn), 9 — Mangala (Mars). This makes each number not an abstract symbol but a personified planetary archetype with its own mythology, qualities, and periods of rulership.

The system's three key numbers are: Mulanka — the "root number," determined from the day of birth (for example, a person born on the 25th has a Mulanka of 7). Bhagyanka — the "destiny number," calculated from the complete date of birth (analogous to the life path number). Namanka — the "name number," derived from the sum of the numerical values of the letters of the name according to the Vedic correspondence table. The combined analysis of the three numbers reveals the person's inner nature, destiny, and auspicious name.

In Errarium, Sankhya Shastra is considered among numerological systems as the one most deeply integrated into the astrological tradition of its culture. While in Pythagorean numerology (#5) numbers are self-sufficient as archetypes, here they are "masks" of the planets. This makes Vedic numerology an instrument that organically complements Jyotish rather than functioning as an independent standalone system.
