The Mundaka Upanishad, another principal Upanishad, declares, Nayam atma bala-hinena labhyo. It means, this atman cannot be achieved or attained by the weak. It is a message to be strong; to go from strength to strength. So, after chanting the mantra along with the final words, “Let truth which is set forth in the Upanishads live in me, and may I grow dedicated to the Self,” the student begins to learn the Upanishad.
