Any form of blessing or metta meditation is deeply therapeutic.
Teacher 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.
Creating Peace on Earth
Begin by inhaling comfortable deep breaths.
Slowly inhale white light, exhaling any darkness.
Your material body is now glowing in bright white light while your etheric double is turning sky-blue.
Your consciousness is becoming lighter and no longer hindered by heavy thoughts and emotions.
Begin to expand your consciousness in every direction from where you are sitting.
It passes out of the building, above the trees, like a growing bubble, until you can see the town in which you live.
A lovely rose light pours out from your Heart Chakra blanketing first your neighbors’ homes then the whole neighborhood and finally the entire town.
You feel joy.
Continue to expand to the point where you can see the entire nation.
Perhaps there is trouble in some part of it.
Your heart continues to pour out love for all.
The whole country is now covered in this misty rose colored light.
Next spread your awareness to encompass first the cloud cover and then the atmosphere.
You can see the whole planet.
It is a gorgeous paradise of deep blue oceans, vast mountain ranges and lush plains.
But you know there is fighting in various parts of the world, great unhappiness, and you want to help.
From where you are, there are no boarders marked, no lines separating people.
It is one world. All trouble is born of ignorance and misunderstanding.
We want to love one another and live in peace.
Now your heart is a river of rose light which floods the areas of trouble on the globe with peace and love.
You see millions of smiling faces bathed in the rose light.
You see men laying down their arms and embracing one another in common brotherhood.
You see people giving food and clothes to the others in need.
Now you see the planet move towards you and nestle in your heart.
Moments ago you were on the planet and now it is in you.
Keep the planet in your heart.
Now return back to your present-day personality and your material body.
Breath deeply until you feel you have fully returned. Wish peace and harmony to prevail the world over.
