Bhagavad Gita 13.17 · Krishna
Undivided, yet in every being
अविभक्तं च भूतेषु विभक्तमिव च स्थितम्।
भूतभर्तृ च तज्ज्ञेयं ग्रसिष्णु प्रभविष्णु च॥
avibhaktaṃ ca bhūteṣu vibhaktamiva ca sthitambhūtabhartṛ ca tajjñeyaṃ grasiṣṇu prabhaviṣṇu ca
Undivided, yet it seems divided among beings. Know it as what sustains them, takes them back, and brings them forth.
What it means
Krishna says Brahman is avibhakta, undivided. Yet it appears divided, as if each being had its own separate piece. Like one sun reflected in a thousand puddles. It sustains all beings, takes them back at the end, and brings them forth again. One reality, many reflections.
The story
Arjuna sees thousands of separate warriors. Krishna says they're like reflections of one light. The separateness is real on the surface, and not the deepest truth.
In your life
After rain, look at puddles reflecting the sun or moon. One light, many reflections. When you meet someone today, remember you share the same light.
One light, a thousand reflections.
