Guru Purnima (IAST: Guru Pūrṇimā, sanskrit: गुरु पूर्णिमा) is a festival traditionally celebrated by Hindus and Buddhists.On this day, disciples offer puja (worship) or pay respect to their Guru (Spiritual Guide). It falls on the day of full moon, Purnima, in the month of Ashadh (June–July) of the Shaka Samvat, Indian national calendar and Hindu calendar. Traditionally the festival is celebrated by Buddhists in the honor the lord Buddha who gave His first sermon on this day at Sarnath, Uttar Pradesh, India. While Hindus celebrate it in the 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, hence their recitations as a dedication to him, 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 dedicated to the expression of gratitude towards 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 halt at one selected place; some also give discourses to the local public. Students of the Indian classical music, which also follows the Guru shishya parampara, celebrate this festival, around the world.

Ravi Shankar (Bengali: রবি শংকর; born Robindro Shaunkor Chowdhury on 7 April 1920), often referred to with the title Pandit, is an Indian musician and composer who plays the plucked string instrument sitar. He has been described as the most known contemporary Indian musician by Hans Neuhoff in Musik in Geschichte und Gegenwart.

Shankar was born in Varanasi and spent his youth touring Europe and India with the dance group of his brother Uday Shankar. He gave up dancing in 1938 to study sitar playing under court musician Allauddin Khan. After finishing his studies in 1944, Shankar worked as a composer, creating the music for the Apu Trilogy by Satyajit Ray, and was music director of All India Radio, New Delhi, from 1949 to 1956.

In 1956, he began to tour Europe and America playing Indian classical music and increased its popularity there in the 1960s through teaching, performance, and his association with violinist Yehudi Menuhin and George Harrison of The Beatles. Shankar engaged Western music by writing concerti for sitar and orchestra and toured the world in the 1970s and 1980s. From 1986 to 1992 he served as a nominated member of the upper chamber of the Parliament of India. Shankar was awarded India's highest civilian honor, the Bharat Ratna, in 1999, and received three Grammy Awards. He continues to perform in the 2000s, often with his daughter Anoushka.
