So long this conception of life will exist, that "I am this body, and anyone who is related with this body, they are my own men, kinsmen, relatives..." This conception of life is the greatest barrier for advancing in spiritual consciousness. Therefore the Vedic civilization is so planned that one has to give up this rascal "own men" conception. That is the vairāgya. It is called vairāgya. Jñāna-vairāgya. Two things required in human life: knowledge and vairāgya, detachment.
