In the early years of meditating, my focus was mostly on visualizing my chakras. But then one day, I could sense myself expanding out of my body, and I had a new sensation - being lifted! It was rather startling and a rather pleasant feeling.The sensation and expanding out of my body continued and happened in almost every meditation from then on. This lasted for several years, and I soon was able to exert more control over this, almost as if I could choose when and how to open the door to leaving my body.
The whole meditation sensation process reminded me of a spiral - starting off small, and learning how, but then with continued practice, expanding skills and abilities, then looping in another direction when something changed. you start off small, and then with more practice, your skills and abilities grow and improve with each loop.
Then, this sensation of expanding in my meditations, just stopped. Soon, a new sensation emerged. I was now aware I could solicit input ANYTIME - not just during a meditation. It was almost as if I could get meditation results anytime or anywhere. It was almost as if I was now in a "constant meditation". I no longer had to "step out and expand" to get the information I sought in a meditation - it was now always "there".
My point is, the meditative process and cultivating Qi will change. It is not a stagnant process. It grows and develops. The process can change, the sensation can change, and how you get results can change, too. It is like a spiral of energy that changes, and as it moves and grows, so do we.
