We feel pleasure when we fulfil our instincts.
There are two secondary instincts – self-preservation and the continuation of life. When we realise both of these instincts, we feel joy, pleasure and happiness. Why? Because these instincts enable us to survive.
But the main instinct is not self-preservation and continuation of life.
The main instinct is love and unity, a feeling of unity of the whole universe and a feeling that the Universe is ruled by One.
And through our aspiring to God we receive not only pleasure, but life, happiness, health, and everything imaginable.
The paradox is that this higher strategic energy which comes through love is not felt by us but we see what is in front of us – our instincts.
When we put the visible form, which is our secondary instincts, in first place, and put the meaning, which is love, in second place, the form initially blossoms like a tree with a lush crown but the roots begin to die.
The result is any civilization which starts to lose faith in God, first has magnificent development in science and technology but later dies. Which is what we see now.
