Thinking only when necessary

Thought must exist, for our lives to function. But inwardly, psychologically as thought breeds pain, sorrow and this constant drive for pleasure - bringing its own frustrations, disappointments, anger, jealousy and envy - thought has no place at all in that dimension, at that level. If one could actually do this: only exercise thought when it is absolutely necessary, and the rest of the time, observe, look. So that thought which is always old, which now prevents the actual experience of looking, could drop away and it would be possible to live totally in that moment, which is always the 'now'. - Talks with American Students
