The material world is nothing but forgetfulness of the original Supreme Personality of Godhead, the creator of everything.
-Shrimad Bhagvatam Canto 4 Chapter 24 Verse 63, Translation and Purport

न यद्वचश्चित्रपदं हरेर्यशो
जगत्पवित्रं प्रगृणीत कर्हिचित् ।
तद्वायसं तीर्थमुशन्ति मानसा
न यत्र हंसा निरमन्त्युशिक्क्षया: ॥ १० ॥

Those words which do not describe the glories of the Lord, who alone can sanctify the atmosphere of the whole universe, are considered by saintly persons to be like unto a place of pilgrimage for crows. Since the all-perfect persons are inhabitants of the transcendental abode, they do not derive any pleasure there.
-Shrimad Bhagvatam Canto 1 Chapter 5 Verse 10
