On this auspicious occasion of Guru Purnima I hereby salute all the teachers who taught me and bow my head in respect of them on the day.
Guru literally means spiritual guide or teacher that paves the way for ignorant. The word has its root from the Sanskrit which describe “Gu” as the darkness or ignorance and “Ru” means removal of the darkness. Hence the “Guru” means the figure that drives people to the field of knowledge from darkness (ignorance).
“Guru Purnima” the festival is celebrated to honor the Guru (teacher, mentor, and guide) who illuminates the lives of his disciples in the month of June-July on the full moon (Purnima)
As per the mythological evidence it is celebrated to mark the birth anniversary of the great sage VED VYAS who made greatest contribution in dividing Vedic hyms into four parts based on their rites, characteristics and teaching them to his four disciples called Paila, Vaisampayana, jamin and Sumantu.
According to the other Vedic lore, on this the lord Shiva became the first Guru ie. Adi Guru while other suggest Gautam Budhha gave his first sermon at Sarnath on this day it is called Dhammacakkappavattana Sutta (Buddhist Text record the first teaching of Lord Buddha.)
In the southern part of the India where people believe that the great sage Vyas reincarnated as Shankaracharya. Hence, devotees worship Shankaracharya instead of Ved Vyas.
Well, as per the modern theory I understand it is celebrated to express gratitude to the religious Guru be it they are in the form of saints, mentor or the teacher. In my home town a large number of devotees gathered round the Sai Temple at Dharmpura singing in praise of Sai Baba of Shridi. While other are celebrating it to offer their mentor like their favourite teachers.
As per the mythological evidence, he was the grandfather of Kauvrav and Pandav and the author of the great epic the Mahabarata (largest poetic composition of the world) it contains 1000 hyms in it.
It was Vyas who divided the Vedas into four parts titled Rig, Yajurved, Sam and Athrav based on its uses of rites and characteristics.
He was the authors of Bharmsutra and all 18 Puran.
