Many great saints, though they attained enlightenment, did not give it directly to anybody. They just preached about the steps to attain it.
Why does God not give enlightenment directly to everyone? Are samskaras (impressions) necessary for this?
Samskaras are necessary. If you are here, it means that somewhere you had the interest and curiosity to come. Without that interest, how could you come here? So, a little bit of samskaras are necessary.
However, only samskaras are not enough. In life, samskaras, opportunities and grace are all needed. Along with these, self-effort is also required.
If you want to come to the satsang but keep lying in your bed, will it help?
So, self-effort, samskaras, opportunities and grace are all needed.
