Guru Tegh Bahadur Ji Gurpurab, also known as Parkash Purab, celebrates the birth of the ninth Sikh Guru, who was born in 1621 in Amritsar to Guru Hargobind Ji and Mata Nanki Ji. Observed on 25 Chet in the Nanakshahi calendar (usually falling in April), the day is marked with Akhand Paths, kirtans, and processions, while devotees reflect on the Guru's teachings of inner peace, detachment, and unwavering faith in Waheguru. His hymns, including the famous "Jo Mange Thakur Apne Te," continue to inspire Sikhs to lead lives of humility, courage, and devotion.
