Spiritual initiation for the soul is like a taking an influenza vaccine (griepprik) for the body. Knowing that certain developments will inevitably come on your path, you would emulate these experiences in a symbolic fashion. Such an initiation would stir up certain processes inside you in a controlled way. As a result you would recognize them and be able to deal with them. When the development actually takes place, you will be able to go with the flow instead of drowning in the waves.
