There is a rhythm in everything in this entire universe. Every microcosm is moving in a rhythm that equilibrates the supreme rhythm of this whole world. The focus of this paper is twofold. The first part attempts to represent the rhythm of the universe from the philosophical perspective of Upaniṣad and define the relationship between the grand rhythm and happiness. The second portion of this paper tries to represent the method of finding the inner inaudible sound practiced in some yogic traditions. It collectively portrays the connection between rhythm or vibration and meditation for acquiring general or absolute happiness.
