What are the similarities and difference between Reiatsu from Bleach and Chakra from Naruto?
I've felt that they both are similar, like it's a part of the individuals' insides/spirit/soul and also it can be sensed from a distance. Generally, the higher the person's Reiatsu or Chakra levels, the stronger that person is. Another similarity is how Chakra and Reiatsu diminishes to zero while dying. However, there are some significant differences which don't make them the same thing with different names.
I want to know both the differences and the similarities between them.
