There is no question of rejecting or doubting the classics of Vaidik astrology, but the fact is that classics tell you about the effect but do not tell you the cause equation of it. The cause equation has to be found out after measuring the same effect of yoga on different parameters or fundamental rules as given in different classics since the basic rudimentary principles almost remain the same it has to be tested on the anvil of these very principles. For example, a two-planet yoga as given in chapter 8 of jataka Parijaat or elsewhere. Let us assume the planets are Sun and Jupiter conditions to look for combustion of Jupiter, if either of two or both own a dushsthaana or be placed in it if they are placed in 5th is in lajjit avasthaa , the very definition says the planet in 5th house with sun, Rahu or Ketu is in lajjit avastha so this negates 5th house association of Jupiter and sun to produce an effective result, Now come the debilitation signs of both in libra and Capricorn the sign lord in both cases is enemy of the two. Sun is Lagna but this conjunction if it does not happen in signs of Leo, Sagittarius and Pisces will have different lord of Sun Lagna and if they are placed in signs of Saturn, Venus the result will again be non-conducive, Avasthaas of the planet are also important, then the Kendra lordship if it happens for Jupiter and the sign of conjunction being same as Kendra the benefic intent of the planet will be eroded, Mansagri opines that the panch maha Pursh yog bhanga occurs if the yoga creating planets be conjunct sun or moon or in other words, the effects are mitigated. Classics provide you with the picture the coloring box of rules lies with you if you color the picture correctly then Monalisa will be Monalisa and not a poor caricature of the same.
I do not consider myself an authority but the purpose is to make an effort to learn what, when, and how of it. Please forgive me for any inadvertent or known faults in my line of thinking please feel free to correct me wherever you feel that I may have overstepped the confines of the subject itself. Image one Jupiter is in lajjit avasthaa,Image 2 Exchange between the Saturn and Jupiter modifies the yoga .image 3 Jupiter is combust, image 4 dussthaan lords in dushsthaana .
