Is Ishsta-devata determined by the family tradition (Kula-Devata) or personal liking or something else? Are there any injunctions of the **spiritual scriptures**? If it is determined by the injunctions of such scriptures, kindly quote the original slokas with meanings.

**Please note that astrogists quote various slokas for determinig Isha-Devata by Aatmakaraka or any other planet's position in the birth charts. But none of the great saints asked for the birth chart or paid any heed to these to initiate their disciples and this is clear from their biographies. So kindly dont quote anything regarding astrology.**
