On ,the occasion of a preternatural sound from the sky, ,of an earthquake, and when the lights of heaven are surrounded by a halo, let him know that ,the Veda study must be stopped until the same hour ,on the next day , even if ,these phenomena happen in the ,rainy season.  -   Guru Nanak     Quotes
