श्रद्धया परया तप्तं तपस्तत्त्रिविधं नरैः | अफलाकाङ्क्षिभिर्युक्तैः सात्त्विकं परिचक्षते
śraddhayā parayā taptaṃ tapastattrividhaṃ naraiḥ . aphalākāṅkṣibhiryuktaiḥ sāttvikaṃ paricakṣate
当那些不渴望结果、心意坚定的人们，以至高之信实践那三种苦行时，他们称之为悦性（萨特瓦）的。
When that threefold austerity is undertaken with supreme faith by people who do not hanker after results and are self-controlled, they speak of it as born of sattva.
三种苦行（Trividham）指身体、言语和心意的苦行。心意坚定（Yuktaih）意味着心意平衡，不受成功或失败的影响。至高之信（Sraddhaya）是指对神的存在、导师的教诲、经典的训示以及自身内在真我（阿特曼）的坚定信念。
Trividham Threefold -- physical? vocal and mental.Yuktaih Steadfast Balanced in mind? unaffected in success and failure.Sraddhaya With faith With belief in the existence of God? in the words of the preceptor? in the teachings of the scriptures and in ones own Self.
