The difference between Amavasya (New Moon light) and Purnima (Full Moon light) is between darkness and light. During Amavasya, the night it is pitch dark. People do not relish this darkness in any way. Darkness invokes fear. It also breeds evil thoughts and provides opportunities for evil deeds. Only evil-minded persons welcome darkness. No good-intentioned persons will welcome darkness. Darkness is a valuable ally for thieves and rogues. Hence only the evil-minded will hail the advent of darkness. The good-intentioned and righteous persons will welcome the advent of the full-moon. The hearts of good persons filled with good feelings are cool like the moon. Children delight in the sight of the moon. Poets are inspired to pour forth the joy in their hearts at the sight of the moon. On the day of the Purnima (full moon) man’s heart is also pure and bright. People should recognize the relationship between the full moon and the mind. The Vedas declare that the moon emerged from the mind of the Virata Purusha (Cosmic Person) and the sun emerged from his eye. The human mind is a reflection of the moon and when there is the full moon the mind blossoms effulgently. Moonlight dispels the darkness of ignorance, drives away fear and confers peace and joy.
