The fire kindled in wood is always the same, although the wood may be of different types. Similarly, the bodies within the material creation may be specifically different according to shape and quality, but the spirit souls within them are not different from one another. The quality of fire, warmth, is the same everywhere, and the spiritual spark, or part and parcel of the Supreme Spirit, is the same in every living being; thus the potency of the Lord is distributed all over His creation. This transcendental knowledge alone can save one from the contamination of material illusion. Since the Lord's potency is distributed everywhere, a pure soul, or devotee of the Lord, can see everything in relationship with the Lord, and therefore he has no affection for the outer coverings. That pure spiritual conception makes him immune to all contamination of material association. The pure devotee never forgets the touch of the Lord in all circumstances. – Srila Prabhupada in purport to Srimad-Bhagavatam (3.9.32)
