Please
explain why we feel sleepy when we reach a calm and peaceful state.
You feel
sleepy because a state of concentration and a peaceful state of
mind when you are sleepy, are very similar. For some people it
is very hard to distinguish one from the other. But I suggest
firstly that you take care in adjusting your sitting posture so
that your back is straight and secondly that you breath in-and-out
more often just to release the excessive carbon dioxide from your
blood. Repeat 'Samma-Araham' at a faster rate and think of the
brightness more at the centre of the crystal ball.
