Bhagavad Gita 10.25
Of the great seers, I am Bhrigu; of words, I am Om; of offerings, I am the silent prayer; among things immovable, I am the Himalayas.
महर्षीणां भृगुरहं गिरामस्म्येकमक्षरम्।
यज्ञानां जपयज्ञोऽस्मि स्थावराणां हिमालयः॥maharṣīṇāṃ bhṛgurahaṃ girāmasmyekamakṣaram|
yajñānāṃ japayajño'smi sthāvarāṇāṃ himālayaḥ||
