Bhagavad Gita 10.1श्री भगवानुवाच भूय एव महाबाहो श्रृणु मे परमं वचः।यत्तेऽहं प्रीयमाणाय वक्ष्यामि हितकाम्यया ॥

I shall repeat what I said before (in the seventh and the ninth discourses). My essential nature and My manifestations have already been pointed out. As it is very difficult to understand the divine nature, I shall describe it once more to you, although it has been described already. I shall tell you of the divine glories and point out in which forms of being I should be thought of.I will speak to you as you are delighted to hear Me. Now your heart is taking delight in Me.The Lord wants to encourage Arjuna and cheer him up and so He Himself comes forward to give instructions to Arjuna even without his reest.Paramam Vachah supreme word. Paramam means supreme, revealing the unsurpassed truth (Niratisaya Vastu which is Brahman).O Arjuna You are immensely delighted with My speech, as if you are drinking the immortalising nectar.
