Human Life Is Meant For Austerity - Prabhupada 1005
Lord Kṛṣṇa said that one who acts for the sake of duty, not for enjoying the fruit, when it is possible . . . now, if you are family man you have to work for maintaining your family, therefore you have to enjoy the fruits of your work. So this is possible only for a person who has completely dedicated for service of the Lord.
So Ṛṣabhadeva recommends that human form of life is specifically meant for austerity, regulative principles, not to do anything according to whims. Very regulative life, that is human life.
