Guru Purnima
Hindus attach paramount importance to spiritual gurus. Gurus are often equated with God and always regarded as a link between the individual and the Immortal. Just as the moon shines by reflecting the light of the sun, and glorifies it, all disciples can dazzle like the moon by gaining from their Gurus.
The full moon day in the Hindu month of Ashad (July-August) is observed as the auspicious day of Guru Purnima, a day sacred to the memory of the great sage Vyasa. All Hindus are indebted to this ancient saint who edited the four Vedas, wrote the 18 Puranas, the Mahabharata and the Srimad Bhagavata. Vyasa even taught Dattatreya, who is regarded as the Guru of Gurus.
In addition to having religious importance, this festival has great importance for Indian academics and scholars. Indian academics celebrate this day by thanking their teachers as well as remembering past teachers and scholars
Hindus celebrate it in honour of the great sage Vyasa, who is seen as one of the greatest gurus in ancient Hindu traditions and a symbol of the Guru-shishya tradition. Vyasa was not only believed to have been born on this day, but also to have started writing the Brahma Sutras on ashadha sudha padyami, which ends on this day. Their recitations are a dedication to him, and are organised on this day, which is also known as Vyasa Purnima. The festival is common to all spiritual traditions in Hinduism, where it is an expression of gratitude toward the teacher by his/her disciple. Hindu ascetics and wandering monks (sanyasis), observe this day by offering puja to the Guru, during the Chaturmas, a four-month period during the rainy season, when they choose seclusion and stay at one chosen place; some also give discourses to the local public. Students of Indian classical music, which also follows the Guru shishya parampara, celebrate this holy festival around the world.
"Guru is Shiva sans his three eyes, Vishnu sans his four arms Brahma sans his four heads. He is parama Shiva himself in human form"
Guru is the God, say the scriptures. Indeed, the 'guru' in Vedic tradition is looked upon as one no less than a God. 'Guru' is a honorific designation of a preceptor as defined and explained variously in the scriptures and ancient literary works including epics. The English word 'guru' has its etymological origin in the Sanskrit term. The Concise Oxford Dictionary of Current English defines it as "Hindu spiritual teacher or head of religious sect; influential teacher; revered mentor".
