धर्मानन्यान्परित्यज्य मामेकं भज विश्वसन् ।
यादृशी यादृशी श्रद्धा सिद्धिर्भवति तादृशी ॥
dharmān anyān parityajya mām ekaṁ bhaja viśvasan |
yādṛśī yādṛśī śraddhā siddhir bhavati tādṛśī ||
(Brahma-saṁhitā: 5.61)
“Completely forsaking [all] other dharmas, serve me alone having conviction. As is [one’s] śraddhā, so is the attainment [one reaches].”
