According to Jeff Chand
"Feeling qi" can be daunting if we are looking for something very dramatic. Truth is, you probably have already experienced qi - when you feel really relaxed, truly happy, excited, content, warm and tingly, or you feel truly Present.
Qi can feel like: -warmth and tingling -heaviness, fullness -lightness, and weightlessness -emptiness -zapping -buzzing -you can feel borderless -cool -or nothing at all 🙂
Everyone is different, and there are no rules of what it should/shouldn't feel like. You should just feel "good!"
Give it time, and it will manifest for you in your way
