No Effect Without Cause In Nature!

When energy level goes down one gets hunger for food For producing energy needed to activate human body; So also, when the throat and lungs get dried up, one gets Thirst needing water to wet and supply oxygen for relief! Hunger and thirst cannot be avoided or stopped once for All till death comes to one at the end of one's life in world; They are all there to give pain and difficulties to our Self So that when they are satisfied one enjoys pleasure in life! The spirit or soul within doesn't have any pain and pleasure; Only through our body we realize those feelings in our life; In one way, due to that fact, from the spiritual state to our Physical state, perhaps we are all created by Nature to know! In Nature, nothing happens without a cause and this cause And effect are like cause and event in history we know sure!
