How Does One Attain Knowledge of the Spiritual World?

What is the feeling and emotional life of man in the ordinary world like? Nowadays it actually has become somewhat trivial to use the expression ‘egoistic’ everywhere, and to say that people in their normal life are egoistic. I do not want to express it in this way, but prefer to say: In their normal lives people are at first closely tied to their human personality, for example, when something pleases us, yes, especially in relation to things which we enjoy of the noblest spiritual creations, things of art and beauty. The saying, there is no accounting for taste, already expresses that much is connected to our personality and depends upon our subjective stance towards things. Check how everything that can please you is related to your upbringing, in which place in the world, in which profession your personality is placed, and so on, in order to see how feelings and emotions are closely connected to our personality. But when one does exercises of the soul, like the ones described, one notices how feelings and emotions will become completely impersonal. It is a great and tremendous experience when the moment arrives in which our feeling and our emotional life becomes, so to speak, impersonal. This moment comes, it certainly comes, when a human being on his spiritual path, inspired by those who undertake his spiritual guidance, allows the following things to really affect his soul. I will now list some of these things that will affect our whole feeling and emotional life in an educational way if someone allows them to work on his soul for weeks, or months.
