Acharya Prashant explains that sensitivity is the way to know when one has enough. He states that we do not consume or do things for their own sake, but to get something from the doing, a fact we often forget. Whether it's being on a campus, visiting a place, buying something, or investing in a relationship, the aim is to attain something valuable and lasting. However, this aim is frequently forgotten, and we begin to see things as ends in themselves. When this happens, one can accumulate things endlessly without ever inquiring whether the accumulation, progress, or experiences are actually delivering anything of value. The solution, he suggests, is to be careful and cultivate the habit of self-observation. While acknowledging that terms like 'cultivation' and 'habit' may not sound spiritual, he emphasizes that practice (abhyas) is the necessary starting point. Through this practice, one starts getting glimpses of love, which makes the process easier. Eventually, one doesn't need to forcefully discipline oneself but practices out of love. This practice of sensitivity involves constantly asking the question, "What am I getting from it?" Acharya Prashant asserts that this approach is a form of sublime selfishness, and to be spiritual is to be sublimely selfish. Since we are all born deficient and sick, it is our responsibility to selfishly think about how to heal and liberate ourselves from our bondages. Every action must be performed under the shadow of the question, "What is it for?" He clarifies that for a seeker, life must be very purposeful, contrary to some traditional spiritual notions of purposelessness. One must ruthlessly learn to drop what has no use, defining 'use' as that which elevates one's consciousness, not material gratification. This constant, unbroken tension is necessary for a 'prisoner' seeking liberation, who cannot afford to simply relax and enjoy.
