There was this research from old people what they regrets most? Answer what they didn't had done.
If we grow older, we had many desires, which we could not live, and the result is, that we get more and more depressed. If we would had felt all of our frustration, we would not be depressed.
Now I want to go one step farer.
If the world would be perfect and we could accomplish everything....
Do you think that this will give us all? Or would it make us total happy?
Or would it make us dependence on material, worldly things?
Can we buy Happiness or Love?
Is it possible that there is true happiness/love beyond of our desires/ worldly things?
Goethe said: Happiness that accompany our whole life and that doesn't matter on worldly things/desires is the true or inner happiness! The same is true also for love... true love doesn't depend on our desires that we get fulfilled, it is just there without reason.
So more we accomplish so more we want!! Or we don't care anymore!!
My guru Osho/Bhagwan said, if we don't accomplish something meaningful on the inner/spiritual/religious path, we become more and more depressed/frustrated, when we grow older. Because we have missed our chance to connect with the divine....
This doesn't mean that we do not live our desires!!! We should live our desires consciously and find out through that: This is not all (Sanskrit: Neti Neti).
There must be something bigger ... And this I call here the Divine!!!
If God would had created a perfect world, who would think anymore on God. (Attar)
Our world is not perfect for the worldly thinking people and so we have to suffer for everything we accomplish or even we could not accomplish.
The most happiest people in the world had been the people, who had been connected to the divine.... Because they have learned to connect with the divine... And this everybody can learn!!!
We don't need to live in celibacy, rather more we chose for ourself the right spiritual methods that makes us happy.... It can start with Trance dancing or a great Dikir Night (Sufi), or with going to a high spiritual loaded place in India, Nepal, Tibet, Turkey (Konya)... and to meditate there, or going to a saint...
