The entire work lies in building a vessel. Scrutinizing and clarifying everything contribute greatly in carving the hole needed for this vessel. Suffering is good because it creates questions in our minds and hearts. It is the source of deficiency that is required for the light to enter.
Light is already surrounding us. It never changes. We change according to our level of perception and understanding. This light is readily available when we are. Once the vessel or the kli is formed, all the light needs to do is settle in the space already provided by this vessel.
The work is realizing the deficiencies which form the vessel.
