If the lord of the 9th or the lord of the 10th respectively own the 8th and the 11th, their association will not give rise to an effective yoga or Raja yoga or if they do not conjoin either in the 9th or 10th house. Moreover, if any planet occupying a particular sign as part of a yoga formation happens to be aspected by the lord of that sign and both occupy auspicious houses then alone a Raja yoga is formed.

Varaha Mihira states that the results of powerless planets are enjoyed in dreams and thoughts only. For any yoga or Raja yoga to produce more effective results the yoga-causing planets possessing requisite six kinds of strength ( Shadbala), must form an immediate relationship with the Lagna ('Ascendant'), which is possible by any one of them occupying or aspecting the lagna or by directly associating with the lord of the lagna but without any one of them being afflicted by either natural or functional malefics, or by a lord of a trikasthana (the lord of the 6th, the 8th or the 12th house).

The results of the yoga or Raja yoga formed owing to a lord of a kendra ('quadrant') (the lord of the 1st, the 4th, the 7th or the 10th counted from the Lagna ('Birth Ascendant') or Natal Moon) and a lord of a trikona ('trine') (the lord of the 1st, 5th or the 9th house) establishing mutual relationship become more pronounced if the lord of another trikona joins them or if their dispositor, preferably the lord of the Ascendant, finds its exaltation in a kendra or a trikona. Therefore, Raja yogas are generally found in the horoscopes of leaders and famous people Īnd reveal their birth to be out of the ordinary.

In doing so they combine the influence of two types of houses - a) those governing personal initiatives and b) those that show good fortune. There are many varieties of Raja yogas but their formation generally involves the 9th, the 10th, the 2nd, the 11th house and the lagna ('Ascendant'), their respective house-lords and their exaltation signs and exaltation lords, which house-lords combining and giving rise to Raja yogas invariably tend to enhance the affairs of the house they occupy, aspect and rule. All such planetary situations and combinations that indicate good fortune, wealth, comforts, exercise of ruling power and political influence gained, either by way of inheritance or acquired through self-effort, are termed as Raja yogas. The term 'Raja yoga' is not defined in the texts dealing with Hindu Predictive astrology.
