1.6.35

यमादिभिर्योगपथै: कामलोभहतो मुहु: । मुकुन्दसेवया यद्वत्तथात्माद्धा न शाम्यति ॥ ३५ ॥

yamadibhir yoga-pathaih kama-lobha-hato muhuh mukunda-sevaya yadvat tathatmaddha na samyati

yama-adibhih
by the process of practicing self-restraint
yoga-pathaih
by the system of yoga (mystic bodily power to attain the godly stage)
kama
desires for sense satisfaction
lobha
lust for satisfaction of the senses
hatah
curbed
muhuh
always
mukunda
the Personality of Godhead
sevaya
by the service of
yadvat
as it is
tatha
like that
atma
the soul
addha
for all practical purposes
na
does not
samyati
be satisfied

It is true that by practicing restraint of the senses by the yoga system one can get relief from the disturbances of desire and lust, but this is not sufficient to give satisfaction to the soul, for this (satisfaction) is derived from devotional service to the Personality of Godhead.
