Bhagavad Gita 11.53

नाहं वेदैर्न तपसा न दानेन न चेज्यया।शक्य एवंविधो द्रष्टुं दृष्टवानसि मां यथा ॥११.५३॥

nāhaṃ vedairna tapasā na dānena na cejyayāśakya evaṃvidho draṣṭuṃ dṛṣṭavānasi māṃ yathā

Neither by the Vedas, nor by austerity, nor by gift, nor by sacrifice can I be seen in this form as thou hast seen Me so easily.
