Bhagavad Gita 10.24 is Chapter 10, Verse 24, in Vibhuti Yoga (Divine Manifestations). Below are the Sanskrit text, a transliteration, a plain-English translation and an explanation.
purodhasāṁ ca mukhyaṁ māṁ viddhi pārtha bṛhaspatim senānīnām ahaṁ skandaḥ sarasām asmi sāgaraḥ
"Among priests, know Me to be the chief, Brihaspati; among warriors, I am Skanda; and among bodies of water, I am the ocean."
What This Means:
Among priests, Brihaspati (guru of gods). Among military commanders, Skanda (son of Shiva, war god). Among waters, the ocean.
Going Deeper:
Each profession or category has its divine peak: the greatest priest, the greatest general, the greatest water body. Wherever excellence peaks, Krishna is visible.
How To Apply This:
In your field, who represents the highest? That excellence is a mirror of the Divine. And aspiring toward excellence in your domain is a form of approaching the Divine.
