nāhaṁ vedair na tapasā na dānena na chejyayā
śhakya evaṁ-vidho draṣhṭuṁ dṛiṣhṭavān asi māṁ yathā||53||

Meaning : Lord Krishna said:

You have now seen this very difficult-to-see form of mine, which even the gods always desire to see. I cannot be perceived like this by studying the Vedas, performing austerities, giving charity, or by sacrifices. But you have been able to see me like this because you are destined, and because I have granted you the vision.
