(Mahabharata, Book 14, Chapter 16) I made thee listen to truths that are regarded as mysteries. I imparted to thee truths that are eternal. Verily, I discoursed to thee on Religion in its true form and on all the eternal regions. It is exceedingly disagreeable to me to learn that thou didst not, from folly, receive what I imparted. The recollection of all that I told thee on that occasion will not come to me now. Without doubt, O son of Pandu, thou art destitute of faith and thy understanding is not good. It is impossible for me, O Dhananjaya (Arjuna), to repeat, in detail, all that I said on that occasion. That religion about which I discoursed to thee then is more than sufficient for understanding Brahma. I cannot discourse on it again in detail. I discoursed to thee on Supreme Brahma, having concentrated in Yoga.
