Srimad-Bhagavatam: Canto 9 - Chapter 1 - Verse 18


यूयं ब्रह्मविदो युक्तास्तपसा दग्धकिल्बिषा: ।कुत: सङ्कल्पवैषम्यमनृतं विबुधेष्विव ॥ १८ ॥


yūyaṁ brahma-vido yuktāstapasā dagdha-kilbiṣāḥkutaḥ saṅkalpa-vaiṣamyamanṛtaṁ vibudheṣv iva


You are all self-controlled, well balanced in mind, and aware of the Absolute Truth. And because of austerities and penances you are completely cleansed of all material contamination. Your words, like those of the demigods, are never baffled. Then how is it possible that your determination has failed?


We have learned from many Vedic literatures that a benediction or curse given by the demigods never proves false. By performing austerities and penances, by controlling the senses and mind, and by achieving full knowledge of the Absolute Truth, one is fully cleansed of material contamination. Then one’s words and blessings, like those of the demigods, are never a failure.
