Ran across an excellent quote on the blessing way from a wonderful book by Omraam Mikhael Aivanov.
Wherever you go and whatever you do, take care to leave only luminous imprints behind you. You are walking or driving down a road: bless that road and ask that all those who pass that way may receive peace and light and be led onto the right path. Why be content to live unconsciously and record nothing but dirt and disorder? Why not try to work like the sun which ceaselessly impregnates the universe with its light and warmth, its life and generosity? Try not to let yourselves be led into chaotic, destructive, negative activities ever again; try to learn how to behave towards creation and all creatures. And everywhere and always, whatever you touch and wherever you go, remember to leave imprints of light and love so that, more and more, all human beings may vibrate in unison with the divine world.
