Deep thinking can lead one to confusion or clarity.
If you just follow your thoughts wherever they take you,
most likely it will lead to confusion. If you observe the thoughts and
acknowledge them, but stay detached (“deep looking” of the Buddhist system) it
is likely to lead to clarity. As pointed out by ancient seers, this is the same
as being a “witness” to the thoughts.
Controlling the mind and staying silent are difficult. Silence
meditation is harder to do and may lead to chasing of thoughts and frustration.
It may even be frightening to some. Deep looking, staying as a non-judgmental
observer of feelings and thoughts, and understanding oneself is more likely to
settle you down. It will lead to clarity and may even lead you to silence.
