What is the difference between chitta shakti and prana shakti? How about looking at muscles and strength? Just think that prana shakti is the muscle and chitta shakti is the strength. Can you separate muscle and strength? No, they cannot be separated, but they can be spoken about individually. Wherever there is a muscle, strength is supposed to exist in that muscle. It is an integrated part. Muscle is the material part and strength is the invisible part.
In the same way, prana shakti is the material component and chitta shakti is the immaterial component. Just as muscle and strength in the muscle coexist, prana shakti and chitta shakti coexist.
If you understand this idea, this concept of muscle and strength, and analyze prana and chitta shakti, the concept will become clearer to you through your own investigation and thought process.
