If somebody takes your legs and catches you and your head down, then it is not very comfortable. This whole material world is like that. It is uncomfortable. It is perverted reflection. On the bank of a river or the bank of a pond, tree is standing, but the reflection in the water, of the tree, is not real. Real tree is up. Similarly, real enjoyment, real varieties — everything is in the spiritual world.

From Srila Prabhupada’s lecture on Bhagavad-gita 15.1 — Calcutta, February 26, 1974
