I am happy to concentrate on what is freedom. When mind is free from conflicts, there we experience freedom. It does mean that we should give up all obstacles that disturb our mind. In this sensual world it is not easy. Therefore we should contemplate of danger of clinging to sensual objects. When contemplation of danger is well practiced, we see how the mind is strong enough to experience detachment. When the contemplation of detachment is well practiced, we experience cessation of defilements. There it is said that we reach the Blissful Destination, called Ultimate Freedom.
