Telescopes have immense capacities in
the external world to show us countless
galaxies. But if one wishes to look inward
to study his thoughts, feelings, and desires,
the telescope is on no use. An instrument
should be used for the purpose it was
designed to accomplish.
Self-discipline is an instrument for
becoming aware of and mastering one's
internal states. The discipline that helps
one gather the dissipated and scattered
forces of mind should be accepted and
practiced regularly. Otherwise the human
mind deprives itself of the awareness of
the higher dimensions of life.
Perennial Psychology of the Bhagavad Gita
