2.3.24

तदश्मसारं हृदयं बतेदं यद् गृह्यमाणैर्हरिनामधेयै: । न विक्रियेताथ यदा विकारो नेत्रे जलं गात्ररुहेषु हर्ष: ॥ २४ ॥

tad asma-saram hrdayam batedam yad grhyamanair hari-nama-dheyaih na vikriyetatha yada vikaro netre jalam gatra-ruhesu harsah

tat
that
asma-saram
is steel-framed
hrdayam
heart
bata idam
certainly that
yat
which
grhyamanaih
in spite of chanting
hari-nama
the holy name of the Lord
dheyaih
by concentration of the mind
na
does not
vikriyeta
change
atha
thus
yada
when
vikarah
reaction
netre
in the eyes
jalam
tears
gatra-ruhesu
at the pores
harsah
eruptions of ecstasy.

Certainly that heart is steel-framed which, in spite of one’s chanting the holy name of the Lord with concentration, does not change when ecstasy takes place, tears fill the eyes and the hairs stand on end.
