Dainya Yoga
Dainya yoga is an exchange of signs between the lords of the 6th, 8th or 12th house and the rulers of any of the other houses. There are thirty such yogas in all. They limit success and well-being and create delays and obstacles in one’s undertakings. A person with this yoga in his chart is marked by foolishness, an unstable mind and immoral behaviour; he insults others and suffers from enemies. Dainya yoga is, nevertheless, not an absolute evil. It certainly raises barriers on a person’s path to success by the hands of his enemies, and it also shows failures in his undertakings. A strong and well-aspected yoga, however, allows a person to gain victory over his opponents and to get round the obstacles that arise.
