Śrīmad-Bhāgavatam · Text 11.23.50
Who is speaking and story frame
जनस्तु हेतु: सुखदु:खयोश्चेत्
किमात्मनश्चात्र हि भौमयोस्तत् ।
जिह्वां क्वचित् सन्दशति स्वदद्भि-
स्तद्वेदनायां कतमाय कुप्येत् ॥ ५० ॥
janas tu hetuḥ sukha-duḥkhayoś cet
kim ātmanaś cātra hi bhaumayos tat
jihvāṁ kvacit sandaśati sva-dadbhis
tad-vedanāyāṁ katamāya kupyet
If you say that these people are the cause of my happiness and distress, then where is the place of the soul in such a conception? This happiness and distress pertain not to the soul but to the interactions of material bodies. If someone bites his tongue with his own teeth, at whom can he become angry in his suffering?
