Bhagavad Gita 4.3

स एवायं मया तेऽद्य योगः प्रोक्तः पुरातनः।भक्तोऽसि मे सखा चेति रहस्यं ह्येतदुत्तमम्॥

sa evāyaṃ mayā te'dya yogaḥ proktaḥ purātanaḥ |bhakto'si me sakhā ceti rahasyaṃ hyetaduttamam ||

That same ancient yoga has been today taught to you by me, for you are my devotee and my friend; it is the supreme secret.

It is the same ancient path that I have now revealed to you, for you are my devotee and my friend. It is the supreme secret.
