(Sanskrit) “The Great Day.” A period of universal activity, as opposed to a Mahapralaya, a cosmic night or period of rest.
"Truthfully, the quantities of years assigned to a Cosmic Day are symbolic. The Cosmic Night arrives when the ingathering of the perfect souls is complete, which means, when the Cosmic Day is absolutely perfected." - Samael Aun Weor, The Pistis Sophia Unveiled
"I was absorbed within the Absolute at the end of that Lunar Mahamanvantara, which endured 311,040,000,000,000 years, or, in other words, an age of Brahma." - Samael Aun Weor, The Revolution of Beelzebub
"Whosoever follows the path of the Perfect Matrimony must develop charity. Cruel and pitiless people do not progress in this path. It is urgent to learn how to love and always be willing to give even to the last drop of blood for others. The warmth of charity opens all the doors of the heart. The warmth of charity brings Solar Faith to the mind. Charity is conscious love. The fire of charity develops the chakra of the heart. The fire of charity permits the sexual serpent to rise rapidly through the medullar canal. Whosoever wants to advance rapidly on the path of the razor’s edge must practice Sexual Magic intensely and give himself totally to the great Universal Charity. Thus, by sacrificing himself absolutely for his fellowman and giving his blood and his life for them, he will be rapidly Christified."
- Samael Aun Weor, The Perfect Matrimony
