Premanand Maharaj Ji
What kind of detachment is needed for moksha?
Detachment from three worlds and three bodies
Moksha is the last level of welfare and auspiciousness; beyond it is fullness, an ocean of bliss with no trace of sorrow. Its practice is detachment from all three worlds and three bodies, and without a guru who gives the practice it cannot be attained.
Detachment from the three worlds and from the three bodies: the gross world and gross body, the subtle body and heavenly world, the causal body and Brahmaloka. One who is detached from all three outside and inside is fit for moksha.
