Thank you for replies. I noticed that it happens spontaneously in relationship to awareness of the body. Probably that is why Buddha talked so much about benefits of mindfulness of the body. I wish I could extend that awareness but I guess I need to keep working on stillness of the mind.
One somewhat related question for you. Do you agree that lots of suffering over extended periods of time can induce certain insight even if samadhi is weak? It seems that suffering can burn ego and it forces to reevaluate beliefs and self identity.
Alexander, this world is indeed fascinating when considering the amount of intelligence that is behind it. Just the beauty of the nature can be quite impressive. At the same time, it is just a bunch of forms and colors. BTW, how did Socrates use insight in difficult times?
