Spirituality in Vedic astrology is the highest domain of human inquiry, governed by the 12th house (Moksha Bhava — liberation), the 9th house (Dharma Bhava — righteous path), the 8th house (occult and mystical knowledge), and Ketu as the primary Moksha karaka.
Ketu (South Node) represents past life spiritual credit, liberation from material world, and natural inclination toward meditation, renunciation, and mystical knowledge. Ketu in the 12th house, or Ketu Dasha in later life, is one of the most powerful indicators of spiritual awakening.
Jupiter (Guru) is the planet of wisdom, dharma, and divine grace. When Jupiter occupies the 9th or 12th house, or forms Hamsa Mahapurusha Yoga (own/exalted in Kendra), it creates a natural teacher, spiritual authority, or guide.
Sanyas Yoga — defined in BPHS Chapter 38 — forms when multiple planets occupy the 12th house or when the 9th and 10th lords combine with spiritual planets (Ketu, Jupiter, Saturn). This yoga indicates a life dedicated to spiritual pursuit, often including teaching, retreating from worldly affairs, or deep contemplative practice.
The Navamsa D9 chart reveals the soul's spiritual mission in this life. Vargottama planets (same Rashi in D1 and D9) carry particularly strong karmic weight for spiritual development.
