Does this technique effective?

@ernst Ah, I see. Thank you ernst for clarifying.

What a coincidence - I've just finished your book, Graha Sutras. It was one of my best reads!

May I inquire whether all the basic principles are required to be met, or is just one sufficient?

1. Should both the Sun and the 10th house be influenced by Saturn, with neutral planets in the 1st house and same gender planets in the 7th house /or neuter + opposite gender planets in 7th house?

   Or would it be acceptable for any one of these conditions to be met—either Saturn influencing the Sun or the 10th house, or neutral planets positioned in the 1st house with same gender planets in the 7th house /or neuter + opposite gender in 7th house—to proceed?

2. Should this be verified against multiple charts or just one? If only one, which one should it be?

   Is there are specific signs or nakshatras of Saturn, Sun or Moon to consider?
