The Sky Beyond the Universe

“Those who are seers of the truth have concluded that of the nonexistent there is no endurance, and of the existent there is no cessation. This seers have concluded by studying the nature of both.” (Bg. 2.16)
Real pleasure is Kṛṣṇa, whereas material pleasure, which is temporary, is not actual. Those who can see things as they are do not take part in shadow pleasure.

“That abode of Mine is not illumined by the sun or moon, nor by electricity. One who reaches it never returns to this material world.” (Bg. 15.6)
