Among all the Hindu festivals, Guru Purnima is highly significant from a spiritual standpoint. Gurudeva, the enlightened instructor, spiritual mentor, or mentor who guides the soul from darkness to light, is celebrated on the full moon (Purnima) of the Hindu month of Ashadha (June-July) on this auspicious day. However, Guru Purnima is significant not just for its cultural and spiritual aspects, but also for its astrological roots, which stem from the profound impact of Jupiter (Guru) on Vedic astrology.
