तपः परं कृतयुगे त्रेतायां ज्ञानमुच्यते ।
द्वापरे यज्ञमेवाहुर्दानमेव कलौ युगे ॥
Penance is the best way to live in the Kruta Yuga. In Treta yuga, attaining knowledge was the best way. In Dwapara Yuga, performing relegious rituals was the way to live. In Kali Yuga (present day) donating generously to the needy is the only right way to live.
