Well i think some of it will be down to how you approach it, i notice that Master Lin talks about Love through the Heart a lot.
I know about this through my Christian beliefs and other Religions as well, and this Love they talk about, it is to do with Compassion for others, this is why there is that Healing Energy that flows through the Heart.
So that is something that is possible to feel, and learn with Qigong.
with the Qigong training it is a practice to open up these Channels, and there are different types of Qigong Training, so it is down to what you are looking for in your life and why you are training, like cause and effect.
I have read that some times Qigong Healing will feel like Heat in your Body, where the Healing is taking place.
