Every good thought or small good action brings with it the blessings of the Karma of happiness. The seed of good Karma will bear fruits that ripen into joy and success in life. When you bring joy and peace into another person’s life, don’t forget you are clearing a karmic debt to that person who had done something good for you at sometime in the past. The bodies have changed through rebirth, but the Soul has not changed. The Soul is omniscient. It can recollect its past through its own state of pure consciousness. It always attracts those Souls with which it has to work to evolve further in order to move along its path of Self-Discovery.
Enjoy your good karma!
