The full moon day in July, the Hindu month of Ashad (July-August) is observed as the auspicious day of Guru Purnima, is celebrated by worshipping our Guru, the spiritual master, who taught us divine love, by performing poojas performed in prostration to him.The right name for this day is Vyasa Purnima.
This day is sacred to the memory of the great sage Vyasa. It was the great sage Vyasa, son of a fisherwoman,(Satyavathi) who classified the accumulated spiritual knowledge of the Vedas under four heads - Rig, Yajur, Saama and Atharva. The credit of composing the authentic treatise of Brahma-sootras to explain the background of Vedas goes to him. He also wrote the eighteen Puranas, the Mahabharata and the Srimad Bhagavata, the stories of our great heroes and saints, to carry the spiritual and moral precepts contained therein to the common masses. He completed the codification of the four Vedas and writing of the eighteen puranas on this day.
This was the day when Krishna dwaipayanaVyasa, author of the Mahabharatha was born. Owing to the passage of time, Vyasa Purnima came to be called Guru Purnima All Hindus are indebted to this ancient saint. Vyasa even taught Dattatreya, who is regarded as the Guru of Gurus. It is in the fitness of things that Vyasa should be looked upon as the supreme preceptor of mankind. Offering of worship to him signifies the worship of all the preceptors of all times."Vyasa" means "to edit" or "to divide")."He divided the Veda into four, namely Rig, Yajur, Sama and Atharva. The histories and the Puranas are said to be the fifth Veda."
Moon is the presiding deity of the mind. That day is Poornima in the true sense of the term, when the mind is filled with pure love. Let your mind shine brilliantly like the moon on a full moon day. This is possible only when you fill your mind with love. Fill your hearts with love. There is no wealth, no Dharma, no meditation greater than love. If you become the embodiment of love, you will become divine.
