Vibhūti Yoga · Verse 25
महर्षीणां भृगुरहं गिरामस्म्येकमक्षरम् | यज्ञानां जपयज्ञोऽस्मि स्थावराणां हिमालयः
maharṣīṇāṃ bhṛgur ahaṃ girām asmy ekam akṣaram | yajñānāṃ japa-yajño 'smi sthāvarāṇāṃ himālayaḥ
Of the great sages I am Bhṛgu; of utterances I am the monosyllable; of sacrifices I am the japa, and of the immovable I am the Himalaya.
Maharṣīṇām — of the great sages — bhṛguḥ — the most ancient, author of the Bhṛgu Saṃhitā. Girām — of words/syllables — ekam akṣaram — “Om”, the single syllable.
Yajñānām — of sacrifices — japa-yajñaḥ — the sacrifice of silent meditation, the highest. Sthāvarāṇām — of immovable beings — himālayaḥ — the snowy mountain, residence of Śiva.
The vibhūti is always the most essential or the highest of each category.
