Bhāva is a term in Jyotisha denoting a fixed zodiacal division of the sky from the perspective of an observer. It corresponds to the concept of "house" in Western astrology. A natal chart is called bhāvachakra
Overview
In almost all traditional practice, the twelve houses of a chart have the same boundaries as the twelve signs in the chart; in other words, each sign is a house in the chart. The beginning of each house is the 0th degrees of the sign and the end is the 30th degree of the sign. What varies from chart to chart is the enumeration of these houses, i.e., which sign is the first house, which is the second, and so forth. This is determined by the position of the Lagna The house in which the Lagna falls is usually the first house of the chart, and the other houses follow it, counter-clockwise, in the sequence of the zodiac. It is possible, however, for the houses to be defined relative to some other factor, such as a planet, a sign, or any other factor. Each of the twelve houses signifies a region of the concerns of life, and the identity of the sign of that house colors what may be expected from that life. More than one system to align houses with signs are recognized in Jyotisha. The most common method is described above, a method that Western astrologers call the whole sign house system; another is Sripathi, introduced by Sripati, akin to a Porphyryhouse system. The modern Krishnamurti Paddhati also incorporates a Placidus house system. The principle of House Division introduced in Sripathi Bhāva System is described as follows: "In the Sripathi system the 1st house cusp is the Lagna, and the 7th house cusp is the Descendant opposite it, the 10th house cusp is at the MC, i.e. Zenith, and the 4th house cusp is at the IC i.e. Nadir. The four quarters divided thus should be divided into three equal parts each, and thus we find the 12 house cusps in Sripathi system. To find the Bhava Sandhis we should divide the distance between the house cusps into halves."
The houses
The names of the 12 houses and the areas of life represented by them are:
Lagna - Nature of Native, Appearance, Health, Character, Purpose of Life, behavior, birth, limbs, head
Mṛtyu - Death & Longevity, Obstacles, Suffering, Sexual organs and sexual attractiveness, Occult, Dowry, Inheritance, Imprisonment, Excretory organs, accidents
Bhāgya - Father, Luck, Higher learning, Philosophy & Religion, Mentor or Guru, Prosperity, Travel, "deeds of virtue"

Vyaya - Expenses, Sleep, Sexual pleasures, Spirituality, Travel & Pilgrimage, Secret Enemies, Imprisonment, Hospitals, Asylums, Liberation, loss foreign residency, feet
Classifications
In general, houses are classified into four categories:
Kendra: the angular houses, that is the first, fourth, seventh and tenth houses. These are very strong houses for grahas to occupy.
Trikona: the houses forming a triangle within the chart with the first house, about 120 degrees apart from one another, that is the first, fifth and ninth. These are the most auspicious houses.
Dusthāna: the less fortunate houses which tend to rule unhappy areas. These houses make no clear geometric connection to the Lagna. Dusthanas include the sixth, eighth and twelfth houses.
Upachaya: "growth" or "remedial" houses, where malefic planets tend to improve, include the third, sixth, tenth and eleventh houses.
Succedent houses are called pāṇaphara, and cadent houses are called āpoklima. In Indian Vedic astrology, also, the twelve houses are called Bhava and have meanings very similar to their Western counterparts. The houses are divided into four 'bhavas' which point to 'mood' or what the house stands for. These four bhavas are Dharma, Artha, Kama and Moksha. These bhavas are called 'purusharthas or 'aims in life.' The ancient mystics of India realized that the austere path of the yogi was not for everyone. They found that each human existence has four worthwhile goals in life:
Dharma – 1st, 5th and 9th Bhavas/Houses – The need to find our path and purpose.
Artha – 2nd, 6th and 10th Bhavas/Houses – The need to acquire the necessary resources and abilities to provide for ourselves to fulfill our path and purpose.
Kama – 3rd, 7th and 11th Bhavas/Houses – The need for pleasure and enjoyment.
Moksha – 4th, 8th and 12th Bhavas/Houses – The need to find liberation and enlightenment from the world.
Theses 4 aims of life are repeated in above sequence 3 times through the 12 bhavas/houses:
The first round, bhavas/houses 1 through 4, show the process within the Individual.
The second round, bhavas/houses 5 through 8, show the alchemy between relating to Other people.
The third round, bhavas/houses 9 through 12, show the Universalization of the self.
