8.1.14

अथाग्रे ऋषय: कर्माणीहन्तेऽकर्महेतवे । ईहमानो हि पुरुष: प्रायोऽनीहां प्रपद्यते ॥ १४ ॥

athagre rsayah karman- ihante ’karma-hetave ihamano hi purusah prayo ’niham prapadyate

in the beginning
rsayah

hetave
for the purpose of
ihamanah
engaging in such activities
hi

prapadyate
attains.

Therefore, to enable people to reach the stage of activities that are not tinged by fruitive results, great saints first engage people in fruitive activities, for unless one begins by performing activities as recommended in the sastras, one cannot reach the stage of liberation, or activities that produce no reactions.
