Guru Purnima is a sacred Hindu festival dedicated to honoring one's spiritual and academic teachers (gurus). Celebrated on the full moon day of the Hindu month of Ashadha (June-July), this festival is observed across India, Nepal, and by Buddhists worldwide. The day is believed to be the birth anniversary of the legendary sage Ved Vyasa, who authored the Mahabharata, compiled the four Vedas, and composed the 18 Puranas — earning him the title of the greatest guru in Hindu tradition. Hence, Guru Purnima is also known as Vyasa Purnima.
The concept of Guru holds supreme importance in Indian philosophy. The word "Guru" literally means "dispeller of darkness" (gu = darkness, ru = dispeller). In the Hindu tradition, the Guru is placed even above God, as it is the Guru who reveals the divine to the seeker. The famous Sanskrit verse "Guru Brahma, Guru Vishnu, Guru Devo Maheshwara" establishes the Guru as the trinity itself — the creator, preserver, and transformer of the disciple's consciousness.
On Guru Purnima, students and disciples visit their teachers, offering flowers, fruits, and dakshina (offerings) as a mark of gratitude and respect. In ashrams and spiritual centers, the day is marked by padapuja (worship of the Guru's feet), satsang (spiritual discourse), and meditation sessions. Many spiritual organizations hold special events where the Guru blesses devotees and imparts teachings. In the Yogic tradition, this day marks the occasion when Lord Shiva, the Adi Yogi (first yogi), became the Adi Guru (first teacher) by imparting yogic knowledge to the Saptarishis.
Buddhists celebrate this day as the day when Gautama Buddha gave his first sermon at Sarnath, known as Dhammacakkappavattana Sutta, setting the "Wheel of Dharma" in motion. Jains observe it as the day when Mahavira accepted Indrabhuti Gautam as his first disciple. This multi-faith observance underscores the universal Indian reverence for the teacher-student relationship.
