12 houses in Vedic astrology (bhavas) explained

Each of the 12 rashis (zodiac signs) forms one house (bhava). Pick a reference point: the sign containing it is the 1st house, the next sign is the 2nd, and so on around the zodiac.

When houses are mentioned without naming a reference, the reference is the lagna, the Vedic ascendant (the sign rising at birth). P.V.R. Narasimha Rao (PVR), author of the textbook Vedic Astrology: An Integrated Approach, writes: 'Lagna is the default reference when finding houses.'

Skybond uses whole-sign houses: each rashi is one whole house.

PVR notes that some astrologers instead use a 'bhava chalit' chart or an equal-house method, in which a house can start in one sign and end in another, and that Sripati's method is also popular. He recommends neither, writing 'Each rasi is a house', and says Parashara taught houses by counting rasis from the chosen reference.

Houses can also be counted from other references, such as the Moon. The same sign can be the 2nd house from one reference and the 6th from another, and each reference colours what the house means.

The Sanskrit names of the houses come from BPHS (Brihat Parashara Hora Shastra, the foundational text of Jyotish, ch. 11): 1st Tanu (body), 2nd Dhana (wealth), 3rd Sahaja (co-born, a sibling), 4th Bandhu (relative), 5th Putra (child), 6th Ari (enemy), 7th Yuvati (young woman, wife), 8th Randhra (opening), 9th Dharma (duty), 10th Karma (action), 11th Labha (gain) and 12th Vyaya (expense).

The table shows a few matters per house, drawn from PVR's list; BPHS ch. 11 gives a parallel list, for example the 1st for physique, appearance and intellect, the 4th for conveyances, relatives, mother and lands, and the 11th for income. Each house actually signifies many more matters than any table can hold. Picking the right meaning for a reading, PVR says, 'becomes easier with experience' and depends on the reference point and the divisional chart (a secondary chart focused on one life area) being read.

Houses can also be counted from other houses. PVR's example: the 3rd house shows younger siblings, and the 4th house is the 2nd from the 3rd, so it can show a younger sibling's wealth and speech.

PVR groups the houses like this: the 1st, 5th and 9th are trikonas (trines), read as prosperity and flourishing; the 1st, 4th, 7th and 10th are kendras (quadrants or angles), read as sustenance and vital activity; the 3rd, 6th, 10th and 11th are upachayas, read as gains and growth; and the 6th, 8th and 12th are dusthanas (also called trik sthanas), read as setbacks and obstacles. The 1st house is both a kendra and a trikona.

PVR adds: trines are the abode of Goddess Lakshmi, who rules prosperity, and quadrants the abode of Sri Maha Vishnu, who sustains the universe. He also notes that if a dusthana is weak, its obstacles will be easily overcome. A dusthana placement is a chart feature to interpret, never a verdict on a person.

BPHS ch. 11 (verses 14-16) says a house is judged partly by what joins or aspects it (an aspect, when a planet casts its gaze on the house) and by its lord: a house prospers when a benefic, such as Jupiter or Venus, joins or aspects it.

The purusharthas spread across the houses like this, per PVR: dharma (duty and righteousness) is shown by the 1st, 5th and 9th; artha (money and career) by the 2nd, 6th and 10th; kaama (desires and how they are met) by the 3rd, 7th and 11th; and moksha (liberation) by the 4th, 8th and 12th.

Each aim's three houses are trines of one another: PVR calls them the trines from the 1st, 2nd, 3rd and 4th houses, so the artha houses, for example, are the artha trikonas.

BPHS lists the indications of all 12 houses in ch. 11 and then gives each house its own chapter (ch. 12-23), followed by the house lords (ch. 24). Komilla Sutton's weeks 10 to 13 cover the Bhava Chakra (the wheel of houses): the twelve houses, their karakas (significators, the planets naturally linked to each matter), meanings and rulers. ACVA's course 104 calls the bhavas 'the final cornerstone of Jyotish'.

B.V. Raman cautions that such descriptions 'are only general in nature and should not be applied hastily'. A list of matters is a starting point for interpretation, not a fixed dictionary to read a chart from.
