Bhagavad-gītā As It Is · Text 17.17
Austerities of body, speech and mind
श्रद्धया परया तप्तं तपस्तत्त्रिविधं नरै: ।
अफलाकाङ्क्षिभिर्युक्तै: सात्त्विकं परिचक्षते ॥ १७ ॥
śraddhayā parayā taptaṁ
tapas tat tri-vidhaṁ naraiḥ
aphalākāṅkṣibhir yuktaiḥ
sāttvikaṁ paricakṣate
This threefold austerity, performed with transcendental faith by men not expecting material benefits but engaged only for the sake of the Supreme, is called austerity in goodness.
