The mental body has an electric quality. It is fast to obey commands and to hold concepts, beliefs, memories, ideas and thoughts. It also holds your power of discrimination (in truth or in judgments).
This body has a relationship with the 6th chakra, your seat of projection, intuition and command. The mind has the essential quality to be faster than time and space, as it transcends both. Mind seeks to be directed and to be given a purpose.
