What is the best position for sleep meditation, lying down or sitting up?

For sleep meditation, lying down is ideal. You are trying to relax into rest, so getting comfortable in bed, on your back or your side, helps your body follow. Sitting upright is better for daytime practice when you want to stay alert. At night, let your position support drifting off rather than staying awake. StillMind’s wind-down practices are built for lying in bed, guiding you gently toward sleep rather than keeping you attentive.
