There is no knowledge that you can learn without pleasure. This pleasure is a part of the joy which belongs to harmony. So if you have an organ that allows you to feel this pleasure, use it, no matter what it is. Because this pleasure will work in a catalytic way and create new reactions. As a soul, you have to know it because there are many ways and you will enjoy this diversity and remember that it’s a characteristic of Mankind. You have the right to have pleasure and if some systems spoil your right, it’s a proof that they are against Humanity. The soul’s pleasure is a right and nothing less.
