Bhagavad-gita As It Is
BG Chapters 1 - 6
BG 4.26, Purport:
The members of the four divisions of human life, namely the brahmacārī, the gṛhastha, the vānaprastha and the sannyāsī, are all meant to become perfect yogīs or transcendentalists. Since human life is not meant for our enjoying sense gratification like the animals, the four orders of human life are so arranged that one may become perfect in spiritual life.
