Acharya Prashant responds to a questioner's gratitude by emphasizing the importance of maintaining the desire for understanding. He explains that the only obstacle to the growth of understanding is the weakening or diversion of this desire. If the desire for understanding is sustained, new depths, wonders, and joys of life will unfold. The key is to simply maintain this desire. In response to another question about "observation" (avlokan) and its connection to Buddha's teaching of "Appo Deepo Bhava" (be a light unto yourself), Acharya Prashant explains that our deepest intention is for a simple, clear, and light life, yet our lives are often filled with stains and burdens. This happens not by nature, but by mistake, due to our ignorance of these burdens. Whatever is worthless or sorrowful in our lives exists only because we are unaware of it. Observation is the process of becoming aware of this. This is because we don't truly want filth; our deep intention is not to maintain it. The problem in life exists only because we don't know about the problem. Acharya Prashant elaborates that observation is the purest and simplest form of meditation. It means to see things honestly, as they are, without any adulteration or self-deception. When one sees with clarity, seeing itself becomes the goal. The power to correct what is wrong becomes active within oneself upon seeing it clearly, because it is not our nature to let things go wrong; our nature is simplicity, alertness, and truth. All the filth in life is present only by mistake, and it exists because we do not observe our lives. He connects this to Buddha's teaching, comparing Buddha to a physician who can only provide medicine (teachings), while the healing power (life force) is within the patient. The patient must respond to the treatment. Buddha's advice to "be a light unto yourself" implies that there is darkness within us. Observation is the honest act of seeing that the inner lamp is not lit. Once this is seen, one will light it themselves, because our nature is light, not darkness. The proof is that darkness brings sorrow, and everyone seeks knowledge and truth. Therefore, to see life honestly is the first step, after which all other work can be done.
