The process of liberation is very nicely explained in this verse. The cause of one’s becoming conditioned by material nature is his thinking himself the enjoyer, the proprietor or the friend of all living entities. This false thinking is a result of contemplation on sense enjoyment. When one thinks that he is the best friend to his countrymen, to society or to humanity and he engages in various nationalistic, philanthropic and altruistic activities, all that is just so much concentration on sense gratification. The so-called national leader or humanist does not serve everyone; he serves his senses only. That is a fact.
