Excerpt:
The spiritual life cannot be imagined as a lifestyle which does not have anything in common with the usual way of living. On the contrary, it has to be understood as a transformed usual way of living. Only the usually lived daily life can be the ”breeding ground“ of the higher life. However, the fruit of this higher life will only appear when a seed is sown. The seed is the noble morality.

All misery accompanying the life of human beings comes from the illusory conviction that the individual is independent. Troubled by this misery, one believes that they have to struggle to preserve their existence. Therefore, they fight with their fellow beings and don’t even think of the fact that their time, as well as their life, is precisely defined by the destiny and these cannot be prolonged in any way, not even by an hour. However, they should understand that the outer happiness sought for can only come from the inner harmony which improves the conditions for coexistence of all human beings. However, for this understanding a change in one’s philosophy of life is needed.
