Bhagavad Gita 15.7
It is only a very small part of My Eternal Self, which is the life of the universe, that draws around itself the six senses, with the mind being the last, which have their source in Nature.
ममैवांशो जीवलोके जीवभूतः सनातनः।मनःषष्ठानीन्द्रियाणि प्रकृतिस्थानि कर्षति॥mamaivāṃśo jīvaloke jīvabhūtaḥ sanātanaḥ|manaḥṣaṣṭhānīndriyāṇi prakṛtisthāni karṣati||
