"My Lord, I Have Been Wondering...
"My Lord, I have been wondering if You could possibly tell me what Your Substance is, and what Your Essence is, and what Your Aspiration means, and what Your Realisation means."
"My child, My Essence is Nectar-Delight. My Substance is Willpower. My Aspiration means that I am the Transcendental Tree. My realisation means that I am the Eternal Climber."
Excerpt from My Lord's Secrets Revealed by Sri Chinmoy
