Śrīmad-Bhāgavatam · Text 11.28.17
Who is speaking and story frame
अमूलमेतद् बहुरूपरूपितं
मनोवच:प्राणशरीरकर्म ।
ज्ञानासिनोपासनया शितेन-
च्छित्त्वा मुनिर्गां विचरत्यतृष्ण: ॥ १७ ॥
amūlam etad bahu-rūpa-rūpitaṁ
mano-vacaḥ-prāṇa-śarīra-karma
jñānāsinopāsanayā śitena
cchittvā munir gāṁ vicaraty atṛṣṇaḥ
Although the false ego has no factual basis, it is perceived in many forms — as the functions of the mind, speech, life air and bodily faculties. But with the sword of transcendental knowledge, sharpened by worship of a bona fide spiritual master, a sober sage will cut off this false identification and live in this world free from all material attachment.
