Mirati Yoga
Mirati yoga is the placement of the owner of the 3rd bhava in a dusthana together with unfavourable planets or under their aspects. Its results: the absence of brothers, of strength and of courage, wrong actions, a hot temper, powerful enemies.

For a yoga to switch on and work, certain conditions must be met: it must not be spoiled by malefics, and the Sun and the Moon must be strong enough in the horoscope
