Research statement

“Penetration means to enter something, not just to stand outside it. When we want to understand it, when we want to understand something, we cannot just stand outside and observe it. We have to enter deeply into it, and be one with it in order to really understand. If we want to understand a person, we have to feel their feelings, suffer their sufferings, and enjoy their joy. Penetration is an excellent word. The word “comprehend” is made up of the latin roots “com” which means “together in mind” and “prehendere”, which means “to grasp it or pick it up”. To comprehend something means to pick it up and be one with it. There is no other way to understand something”

from The Heart of Understanding by Thich Nhat Hanh.
