1.
The definition of hado is a power to dip inside into the spiritual realm to gain the healing and transforming powers of the life-force energy.
This power can be used to heal or destroy life, depending on how it is used.
There is a good side and a dark side to the power of Hado both being equal in strength since it comes from the same source.
You would most likely see this example in Street Fighter With Ryu or Akuma.
Hado-Ken!!!!!!!!!!!
