Channeling energy is an age-old occult practice. Demons use energy as one of the ways they can move from place to place. They use this energy movement to transfer from person to person, person to object, etc. It is a form of witchcraft, and it is not a practice that brings a person into alignment with the Spirit of God. Even meditation is a form of moving energy as you are trying to move your energy into a certain direction, thought pattern or process in order to gain something. That is witchcraft.
Doing these Eastern spiritual practices is aligning yourself with the kingdom of darkness. It is practicing inviting the demonic into your being and into your life. It can cause great harm to your physical being as well as your spiritual being. Once you bring these practices into your life, you are also inviting these demonic entities into your home and your family. Yoga in particular is very dangerous because of the momentum it has gained in our world today, even within the Christian church.
