Śrīmad-Bhāgavatam · Text 11.3.26
Who is speaking and story frame
श्रद्धां भागवते शास्त्रेऽनिन्दामन्यत्र चापि हि ।
मनोवाक्कर्मदण्डं च सत्यं शमदमावपि ॥ २६ ॥
śraddhāṁ bhāgavate śāstre
’nindām anyatra cāpi hi
mano-vāk-karma-daṇḍaṁ ca
satyaṁ śama-damāv api
One should have firm faith that he will achieve all success in life by following those scriptures that describe the glories of the Supreme Personality of Godhead, Bhagavān. At the same time, one should avoid blaspheming other scriptures. One should rigidly control his mind, speech and bodily activities, always speak the truth, and bring the mind and senses under full control.
