Moon yogas
केमद्रुम योग
No true planet in the 2nd or 12th from the Moon (the Sun and the nodes do not count).
The unsupported Moon. Popular astrology sells this one with fear; the texts themselves list generous cancellations — a planet in a kendra from the Moon or from the lagna, the Moon aspected by Jupiter, the Moon in a kendra, and others — and most charts that technically show Kemadruma also show a cancellation. Read the cancellation line below before reading anything else.
