Enlightenment requires awareness of one's inner Life Force; without it the body collapses and there is no consciousness or mind.
Contemplate one's inner self, the body and mind from the inside, through observation and "feeling" for the I Am sensation of being alive and present. Once located, just rest there, abide there.
But one can accelerate the awakening of the Life Force or vital breath by deeply loving someone who feels it strongly and can express or share it.
This Satsang tape is on how to realize the Life Force, especially with respect to Nisargadatta and Robert Adams.
