Bhagavad Gita · 11.53

नाहं वेदैर्न तपसा न दानेन न चेज्यया।शक्य एवंविधो द्रष्टुं दृष्टवानसि मां यथा॥

nāhaṁ vedair na tapasā na dānena na chejyayā śhakya evaṁ-vidho draṣhṭuṁ dṛṣhṭavān asi māṁ yathā

Neither by the study of the Vedas, nor by austerity, nor by charity, nor by rituals can I be seen as you have seen me.
