Deity worship, pujas, mantra recitation, bhakti marga (nama recitation), all deals with Bhakti yoga or for those of an emotional temperament.
Kriya yoga deals with Raja Yoga or yoga of mysticism.
Both are different paths to the same goal of annihilation of karma, and attainment of liberation or Self-realisation.
Lahiri Mahasaya attained enlightenment through Raja Yoga.
It appears to me that self-realization as in the state of 'samadhi' is possible only for those who follow Raja-yoga, am I correct?
I am assuming that kriya yoga deals with the chakras, and of the great Kundalini yoga.
I am not sure if a pure bhakta can ever attain samadhi or feel the effects of self-realization.
All I wonder about is, whether Raja-yoga quickens the spiritual process and elevates us to a reality that is far higher than a bhakta can attain...
Any thoughts, kindly share.
