Guru Purnima
Guru Purnima, also known as Vyasa Purnima, is celebrated to honor Gurus, who are teachers, mentors, or spiritual guides. It's a day of gratitude for their wisdom and guidance, and is observed on the full moon day in the Hindu month of Ashadha. Additionally, it commemorates the birth anniversary of Veda Vyasa, the sage who compiled the Vedas.
The primary reason for celebrating Guru Purnima is to express reverence and gratitude towards those who have guided and enlightened others through knowledge and wisdom. This can include spiritual teachers, mentors, or any individual who has imparted valuable knowledge.
