Bhagwad Gita
Chapter 11, Verse 53
नाहं वेदैर्न तपसा न दानेन न चेज्यया।
शक्य एवंविधो द्रष्टुं दृष्टवानसि मां यथा।।11.53।।
The form which you are seeing with your transcendental eyes cannot be understood simply by studying the Vedas, nor by undergoing serious penances, nor by charity, nor by worship. It is not by these means that one can see Me as I am.
