Śrīmad-Bhāgavatam · Text 11.16.42
Who is speaking and story frame
वाचं यच्छ मनो यच्छ प्राणान् यच्छेन्द्रियाणि च ।
आत्मानमात्मना यच्छ न भूय: कल्पसेऽध्वने ॥ ४२ ॥
vācaṁ yaccha mano yaccha
prāṇān yacchedriyāṇi ca
ātmānam ātmanā yaccha
na bhūyaḥ kalpase ’dhvane
Therefore, control your speaking, subdue the mind, conquer the life air, regulate the senses and through purified intelligence bring your rational faculties under control. In this way you will never again fall onto the path of material existence.
