Bhagavad Gita 10.25

महर्षिणां भृगुर्हं गिरमस्म्येकमक्षरम् |
यज्ञानां जपयज्ञोऽस्मि स्थावरानां हिमालय:

Translation

I am Bhrigu amongst the great seers and the transcendental Om amongst sounds. Amongst chants know Me to be the repetition of the Holy Name; amongst immovable things I am the Himalayas.
