Pandits, the religious scholars, study the books of the Vedas. Some become renunciates, and bathe at sacred shrines of pilgrimage. Some sing tunes and melodies and songs. This world is polluted with egotism. The realm of Shiva, the realms of Brahma and Indra as well - no place anywhere is permanent.
Religious rituals are all just egotistical displays.
By pleasing and appeasing people, no one is saved. Nanak, when one joins the Society of the True Guru, then the bonds of the terrifying world-ocean are broken. My mind is attuned to the Lord of the Universe. He is my sacred shrine of pilgrimage, fasting and austere self-discipline. The Lord saves, and carries across, those who meet with the Guru.
