Premanand Maharaj Ji
What is moksha and how is it attained?
How moksha is attained
Take refuge in a sadguru and do the sadhana as he directs. As sin and attachment fall away, the world loses its hold, and vairagya (detachment) and anuraag (deep love) for Bhagwan's feet bring true realisation. Moksha comes by Bhagwan's kripa (grace), and it cannot be attained without love for Bhagwan.
As you keep practising, sin and attachment are destroyed and the world stops feeling pleasing. When vairagya from the world and anuraag at Bhagwan's feet both come, tattva bodh happens by itself.
