BG 2:25. This (Self) is said to be unmanifested, unthinkable and unchangeable. Therefore, knowing This to be such, thou should not grieve.we are the atma but should not be called as atma as per vedic description of ATMA...Because we the atma are not controlling the heart beat.
How do you know Atman is not controlling the heartbeat? Your mind is making unwarranted assumptions about the Atman, chant Hare Krishna and calm it down
