What is satisfactory hearing? When we listen to the television? Or the Srimad Bhagvatam? So Srila Prabhupada in this purport (SB 2.6.46) stresses hearing about the Lord.
He says that one cannot be fully satisfied by hearing, unless and until, one is given a chance to hear the transcendental activities of the Lord.
Every living entity has a tendency to hear some pleasing messages and as such, almost every one of us is inclined to hear news and talks broadcast by the television and radio stations.
