How can we keep track of time during meditation at home?

According to Osho, you don’t need a clock: rely on your inner biological watch. Set a clear intention for the session’s length and simply estimate; within five to ten days your sense of timing stabilizes. Minor variance (eight or twelve minutes for a ten-minute sit) is harmless. Practice rekindles trust in the natural inner rhythm that wakes, eats, and meditates on time.
