Sexual stumbling blocks.

Mr. Gurdjieff once pointed to one of his pupils
who was lost, staring at an attractive young woman,
a pupil of Mr. G's, also in the same room.
Gurdjieff said, "take this young man here, his
attention is three quarters gone".

This young man, was quite new in the group,
and was doing what all young men do, but the
work teaches us that we have to learn to become real.
BE a real man, or a real woman.
Not fascinated children, those who sexually attract us
are one of our biggest stumbling blocks.
