Thank you so much for your kind words, S M Mamunur Rahman.
Reiki is intelligent cosmic energy. ‘Rei’ means universe, ‘Ki/chi’ is energy. Everything in this universe is made of energy, be it the air we breathe, our body, soil, mountains, or stars.
The healer is just a conduit through which this energy passes on to any person, place, or situation. Healer at the time of attenuation connects with this energy in form of symbols. Through these symbols, healing is transmitted.
Meditativeness is good, not mandatory.
I hope it helps.
