In a high-frequency life, controlling and evolving your mind is the most important factor. You are more likely to think unconsciously than act unconsciously. So, first thing is to start paying attention to your thoughts. You need to be in constant awareness of what is going on in your mind.
All thoughts are energy in the astral dimension. Even though you cannot see this energy without strong clairvoyance, you may be able to feel them. Most humans by adulthood, have developed high enough sensitivity to sense certain energies directed at them.
From the root chakra to the crown chakra, from your higher self to the spirits around you, there are a plethora of ways for thoughts to enter your mind. Once there, in your mind, thoughts gain power. The longer they reside in your mind, the more energy they build.
