General Enunciations of Yogas and its theory

• Yoga
  planets though attaining negative character still retain their yoga character.
• Yoga
  planets or those that are in their stars give beneficial effects while Avayoga
  ones give malefic results.
• Yoga
  planet must be in positive Rāśi, Bhava or Star while
• Avayogi must be in negative Rāśi, Bhava or Star or Eclipsed.
• If 6, 8
  and 12 Bhavas are Zero Rāśis, good results arise; viz. no enemy, no debt and no
  loss.
• Positive
  planets in negative Rāśis give tolerable good results when retrograde.
• Negative
  planets should not be retrograde as they become more powerful to do evil.
• Rahu and
  Ketu are natural negatives. When they are in Zero- Rāśis they become extremely
  good. Of them Rahu is exceptionally good.
• Weigh
  your judgement from the position and condition of the steller lord.
• Negative
  planets in Zero-Rāśi or negative Rāśi or Bhava are good but become bad if they
  are retrograde.
• Of the 2
  Rāśis owned by a planet (except Sun and Moon who own only one Rāśi) that Bhava
  which is Zero-Rāśi suffers and not the other. If that planet is powerfully and
  positively situated it does more harm to the Zero-Rāśi-Bhava but may give good
  of the other Bhava. If on the other hand such a planet be negatively placed or
  eclipsed the effect of the Zero Rāśi-Bhava becomes good while the other goes
  bad.
• Planets
  in conjunction with or aspected by Yoga or Avayoga planet imbibe their
  character also in addition to their own.
• Duplicate
  Yogi in the star of birth yogi or vice-versa confers high yoga.
• Avayogi
  in enemy’s star is good.
