1st house in Vedic astrology: meaning and significations

P.V.R. Narasimha Rao (PVR), author of Vedic Astrology: An Integrated Approach, lists these matters for the 1st house: physical body, complexion, appearance, intelligence, strength, energy, fame, success and nature of birth.

The Brihat Parashara Hora Shastra (BPHS, R. Santhanam's translation), chapter 11, gives a closely matching list for the Tanu Bhava: physique, appearance, intellect, complexion, vigour, weakness, happiness, grief and innate nature, 'all to be guessed through the ascending Rāśi' (the sign of the ascendant).

The two lists overlap on body, appearance, intellect and innate nature.

PVR also notes that each house shows many matters, and picking the right one for a given question 'becomes easier with experience'.

A karaka is a planet that signifies a matter. Every house has a natural significator (naisargika karaka), a planet traditionally linked to that house's themes.

PVR's Table 15 gives the Sun as the primary naisargika karaka of the 1st house, for self, physical constitution and soul.

Karaka planets also give houses a second reference point. PVR gives the example that 'the 4th house from Moon shows mother', so houses can be counted not only from the ascendant but from the significator's position as well.

Houses are sorted into groups. The 1st house belongs to several at once.

• Kendra (quadrant or angle): houses 1, 4, 7 and 10. PVR calls kendras houses of sustenance and vital activity, and says quadrants 'are the abode of Sri Maha Vishnu', sustaining each other: self (1st), comforts (4th), marriage and others (7th) and profession (10th).
• Trikona (trine): houses 1, 5 and 9. PVR summarises trikonas as houses of prosperity and flourishing, and says 'Trines are the abode of Goddess Lakshmi, who rules prosperity'.
• Aim of life: the 1st, 5th and 9th form the dharma trikona. Dharma means duty or righteousness, one of the four aims of life (purusharthas).
• Invisible half: houses 1 to 6. PVR says visible-half houses (7th to 12th) 'give results that can be seen in the material world', while invisible-half houses 'give results that cannot be easily seen'.

As a quick contrast from the same source: upachayas (growing houses) show gains and growth, and dusthanas (difficult houses) show setbacks and obstacles.

The lord of a house is the planet that rules the sign sitting in it. Because the ascendant's sign varies from chart to chart, so does the 1st lord.

BPHS ch. 34 speaks highly of this lord: 'The Lord of Lagn is specially auspicious, as Lagn is a Kendr, as well as a Kon' (Kon means trine). PVR adds that the lagna lord 'represents the physical self of a native', and that the lagna itself is the default reference when finding houses and 'shows true self'.

For judging any house, BPHS ch. 11 gives a general rule: 'Predict prosperity of the Bhava, which is yuti with, or drishtied by a benefic' (yuti means joined by a planet; drishti means a planet's aspect or gaze; a benefic is a traditionally favourable planet). A house also does well when its lord is strong or in the 10th house, and is harmed when its lord is with a malefic (a traditionally difficult planet) or with the lords of the 3rd, 6th, 8th, 11th or 12th.

The 1st house is important enough that BPHS gives it its own chapter, ch. 12, 'Effects of Tanu Bhava'.
