I have read that some folks claim that when they experience kundalini rising (not sure if it was thru a scientific method or it was spontaneous), they feel "orgasmic" feelings thru each chakra as it moves up the spine. Again PY doesn't talk this way, but does allude that the feeling is better than any physical feelings. I wonder if the former folks actually do feel that way, and they have awakened kundalini, or it has awakened on its own, and some kind of karma or attachment need to be worked out. This is one example where it could be a little dangerous, and maybe lead you the wrong way.
I haven't personally experienced the feeling quite like that, but I would say it is different and at times equally as powerful and satisfying. The problem with that I think is, that's when you get attached to a feeling, hard not to.
There are some feelings that r good to b attached to because they r healthy and inspiring. They r helpful to spiritual growth. i would say that such feelings that r given to us by God r such feelings. There r a few people in our lives that have really made our lives special by their presence... i would put these feelings in such a category. However these r often bittersweet because these people do not have the staying power to overcome the hurtles with us. Yet occasionally we do meet people who remain friends for a lifetime.
If one ever has a strong spiritual experience it never leaves u. That experience transcends any experience you have on this earth. It is a shining lite as an example for your life and for everything you do, think and accomplish. You realize that you really have only tapped into the love and light of God. You realize how much you have yet to accomplish to be in that type of joy just one more time. You never forget it. That feeling is there as a reminder every day of your life. You will never give up the search for God again. Because you realize that without being in that state again your life will never be complete. Every person..every situation..every circumstance becomes a chance and a reason to find that lost love again and to never loose it even if it is a small reminder as this post is... it provides a door to open and take you back home to love. You realize who you really are. You r love and you must express it in every way you can so that it becomes a permanent presence in your life.
