Recently I have experienced a beautiful meditation experience. I couldn't sleep one night, so I started meditating at 4'0 clock. after sometime my breath disappeared and my physical body boundaries disappeared. I did not feel the separation between the air around me in the room and my body, felt my body is that air/ energy!!! though I am thinking that my body boundaries have gone, that peaceful experience was still strong(Usually when thoughts start popping up, meditation experience goes). After sometime felt heaviness in my heart and could not sit in meditation. After getting up from meditation also I was so fresh, as if I had a deep peaceful sleep and did not find the need to sleep afterwards. Could you please tell me the reason for heaviness in my heart and at what time do you get up to meditate? I heard that 4AM is good time to meditate. I would be grateful if you could explain the disappearance of physical body boundaries, what does that mean?
Early morning has been prescribed as the ideal time for meditation by sages throughout the ages since it is the quietest time of day. It is said to have a special fresh energy associated with it that makes it especially good for meditation. Your experience of physical unboundedness and breath suspension are strong indicators of a deep meditation. The subsequent feeling of heaviness in your heart shows that you released some very profound emotional blocks earlier in your meditation and that gave rise to that heavy feeling. This experience is also good in that it means you are clearing away the old conditioning from your past and opening yourself up to even deeper and longer periods of profound silence in meditation.
