Acharya Prashant explains that the present moment means reality. We are always in the present; we do not have to make an effort to be in it. What pulls us away from this reality is our own organized lie. Therefore, to live in the present means to not give patronage to falsehood. Living in the present does not mean what is commonly propagated by many authors and gurus, which is to not think about the past or the future. We have the right to think about both. Memories are not useless; without them, there can be no conversation or language. The meaning of the present is not the erasure of memories from the mind. The present means 'that which is'. When you are established in 'that which is', even your imaginations are auspicious and pure. When you are in that state, you can talk about the past and future, but it is just talk, not a spiritual hope. You will not talk as if bliss was in the past or will come in the future. When the past and future are just segments of time, there is no harm in talking about them or remembering them. However, when the past and future become a means for your spiritual gratification, they become your hell. This happens when you think, 'Oh, those were the days!' or 'I am weak now, but tomorrow heaven will descend.' A person lives in incompleteness in two ways: either by thinking that some other person will bring them fulfillment, or that some other moment will. When neither of these two feelings is present, it is said that the person is living in the present. Living in your completeness is called living in the present. The questioner asks how to manage the memories of the past and the fear of the future. Acharya Prashant likens this to a drunk person asking a doctor how to get sober while continuing to drink. The question itself is dishonest. The real question is not how to get out of this state, but why you keep getting into it. You have made arrangements to keep yourself intoxicated with these thoughts, for instance, by constantly checking your phone for the next distraction.
