Acharya Prashant addresses a student's concern regarding mobile phone addiction and constant distractions from social media notifications. He clarifies that the device itself is not the problem; rather, the issue lies in what the user is doing on the phone and the quality of the people they interact with. He points out that if notifications from friends are a constant nuisance, the real problem is the choice of company. He explains that people often hide their true nature initially, and it is only through closeness that their lack of substance becomes apparent. Therefore, the solution is not just to avoid the phone, but to be more discerning about whom one allows into their life.
