महर्षीणां भृगुरहं गिरामस्म्येकमक्षरम्। यज्ञानां जपयज्ञोऽस्मि स्थावराणां हिमालयः ॥

maharṣhīṇāṁ bhṛigur ahaṁ girām asmyekam akṣharam yajñānāṁ japa-yajño ’smi sthāvarāṇāṁ himālayaḥ

Of the great Rishis Bhṛigu; of speech I am the one syllable; of sacrifices I am the sacrifice of silent repetitions; of immovable things the Himâlaya.

In plain words: Krishna says that among great sages He is Bhrigu. Among words, He is the one sacred syllable Om. Among offerings, He is the quiet repeating of a holy name or prayer. Among things that do not move, He is the Himalaya mountains.
