Unconditional Love is Eternal happiness, Ananda.
Happiness in most of our life is temporary because of the very conditional in nature. Loving everyone without any selfish expectations brings Eternal happiness.
Living a life of unconditional love, helps us to realize our own true potential and experience it as Peace or Eternal Happiness. In Spiritual languagethis state is referred to as Self and religious language as "Divine God" and Science yet to connect it to Consciousness, the mystery still unsolved.
We join hands with everyone to share this unconditional love, through community service or Selfless work. There are several ways to express this unconditional Love. We welcome you all to work together for this mission, because We are all Cells in One Cosmic Body.
Not doing selfess work is cancerous: The way we feel ourselves changes according to the Individual. If we pay attention for a few seconds and think who we are, we understand that we are just a group of 50 to 70 trillion cells, working in a coordinated manner, sharing all resources and work. Understand that when one cell feels that it does not want to share any resources with others and also work, then it becomes cancerous and destroys the whole body.
We dislike one single cell of ours to behave as a cancer cell in our body, but we are beaving as cancer cell to this Cosmic body. This is why throughout mankind there was is emphasis on selfess work. For many years this was ignored as a philosophical thought, untill recently now scientific are thinking as a scientific reality (click the latest article).
We speak about Selfless work at all levels, because the advantage of it goes beyond the scientific intelligence to Awareness. Selfless attitude increases our own Self-Awareness energy, the energy fuel to make our life happy. Even doing selfless action with a selfish motive in the begining later blossoms into Un-conditional love to experience the unconditional nature of our own Self, the realm of no-suffering but only peace and unconditional happiness. This is not a state that is attained after death, but begins right while we are living.
