Any form of blessing, or metta meditation, is deeply therapeutic.
Master Choa writes about this:
“When you transform despair into hope, and doubt into faith, you find that even in difficult situations, you are filled with great strength. Transforming Darkness into Light and Sadness into Joy fills you internally with Light and with inner joy.
When you seek to console, you are filled with light, love and power instead of wallowing in your own selfish misery and pain.” (Beyond the Mind – Golden Lotus Sutras, Master Choa Kok Sui.)
The following beautiful meditation is given by a great Christian mystic and healer Dr. Stylianos Atteshlis a.k.a. Daskalos.
