I have
started to meditate on the crystal ball at the centre of the body.
In the last four days I have learned the meditation from you,
the size of the crystal ball has remained constantly at a diameter
of eight centimetres. When will it grow smaller and smaller?
You are very
successful in meditation indeed. Don't worry about the size of
the crystal ball too much. Let it remain there and be clear, and
then after the awareness has become one with the crystal ball
you will be able to control the size of the crystal ball according
to your intention. At this stage you have made a slight progress
in your meditation. I congratulate you on your success!
