Guru Purnima

The day of full moon, Purnima, in the month of Ashadh of the Hindu calendar is traditionally celebrated as Guru Purnima (IAST: , sanskrit: गुरु पूर्णिमा) by Hindus. On this day, devotees offer puja (worship) to their Guru.
This was the day when Krishna-dwaipayana Vyasa – author of the Mahabharata – was born. Veda Vyasa, did yeoman service to the cause of Vedic studies by gathering all the Vedic hymns extant during his times, dividing them into four parts based on their use in the sacrificial rites, and teaching them to his four chief disciples – Paila, Vaisampayana, Jaimini and Sumantu. It was this dividing and editing that earned him the honorific "Vyasa" (vyas = to edit, 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."
- Brahmanda Purana 1.4.21 
The spiritual Gurus are revered on this day by remembering their life and teachings.
Seekers try to get as much opportunity to do Satseva of the Guru as possible during this period. As the Guru principle is 1000 times more active during this period, when compared to any other day during this year, the satseva done on Guru Poornima fetches substantial grace of the Guru for their spiritual progress. (Ref : Sanatan Prabhat)
The relationship between the Guru and the Disciple is considered very sacred. This relationship is purely spiritual in nature and is independent of age of the two. It is based on maturity of Gyan (Spiritual Knowledge) and Sadhna (Spiritual Practice). The only awareness that a Disciple should foster is, ‘I should be uplifted spiritually’. The Guru too harbours only one thought, ‘May this Disciple be uplifted’. Relationships other than Guru-Disciple are bound by worldly restrictions wherein the ego constantly manifests itself while Gyan and other Sadhna have no value. Since these worldly relationships presuppose ego for their sustenance, such relationships are albeit false on the spiritual level. (Ref : Sanatan Prabhat)
