11.23.50

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

janaḥ
these people
tu
but
hetuḥ
the cause
sukha-duḥkhayoḥ
of my happiness and distress
cet
if
kim
what
ātmanaḥ
for the self
ca
and
atra
in this conception
hi
indeed
bhaumayoḥ
they pertain to the material bodies
tat
that (status of being the performer and the sufferer)
jihvām
the tongue
kvacit
sometimes
sandaśati
is bitten
sva
by one’s own
dadbhiḥ
teeth
tat
of that
vedanāyām
in the distress
katamāya
with whom
kupyet
can one get angry

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?
