Bhagavad Gita 15.15 — God in every heart
सर्वस्य चाहं हृदि सन्निविष्टो मत्तः स्मृतिर्ज्ञानमपोहनञ्च। वेदैश्च सर्वैरहमेव वेद्यो वेदान्तकृद्वेदविदेव चाहम् ॥
sarvasya cāhaṃ hṛdi sanniviṣṭo mattaḥ smṛtirjñānamapohanañca | vedaiśca sarvairahameva vedyo vedāntakṛdvedavideva cāham ||
Meaning
I dwell in the hearts of all. From Me come memory, knowledge and their loss. I am the One to be known through all the Vedas; I am the author of Vedanta and the knower of the Vedas.
In today's life
When the right thought comes or understanding suddenly dawns, see it as grace from the God within and be thankful.
