Mercury in Taurus: the fourth house for Aquarius rising

The 4th house, home, mother, property and inner peace, is always Taurus when Aquarius rises; it is an angle (kendra). Taurus adds steadiness, sensuality and a wish to build something lasting. Moon signifies this house by nature, so its condition adds to the picture. The same lord, Venus, owns the 9th too, tying the two houses together.

Mercury in the 4th brings education, a home full of books or study, and property gained through intelligence or trade. Its dignity here: in a friend's sign, ruled by Venus. It cooperates well with the sign lord. Mercury always travels close to the Sun, so the Sun is in this house or next to it; if both are in Taurus, read Budha-Aditya yoga and check how close they are.

• 10°–23°20′ Taurus: Rohini, ruled by the Moon, lord of the 6th here, which brings work, health and rivals into it; its gift is fertility of ideas and things, its shadow attachment and possessiveness.
