Acharya Prashant addresses a question on how to say "no" without feeling guilty. He begins by defining guilt as an admission of being in the wrong. He explains that, taken deeply, guilt is an admission that one is siding with the false and the unreal. Therefore, if one is saying "no" to something false, there is no reason to feel guilty. When one feels they could have helped someone despite having their own work, Acharya Prashant advises letting this guilt become a medium for self-improvement. If you realize you could have acted better, you should let that thought remain so that the next time a similar situation arises, the memory of guilt can be useful. Coming from the right center with the right intention, guilt can be very useful and even transformational, as it makes you realize that you can be better than you currently are. Guilt should signify that you could have performed to a higher standard. The speaker encourages remembering this and allowing the guilt to help and change you. This way, the next time a similar situation occurs, you can perform better. However, he also cautions that one does not need to say "yes" to everything. Feeling guilty needlessly is as much a problem as not feeling guilty when improvement is needed. The speaker concludes by explaining that since guilt causes suffering and hurts self-esteem, one should derive some benefit from it. The benefit of guilt is the decision to improve. If you realize you did something wrong, you can decide to correct yourself the next time. In this way, guilt becomes useful and serves as a medium for transformation.
