Acharya Prashant explains that one should focus on remembering what is meaningful rather than the trivial. He distinguishes between memory as a mental record and 'Surati' or spiritual remembrance, which happens naturally when one is deeply immersed in 'Satsang'. He uses the metaphor of sugar dissolving in water to describe how a seeker should merge with the truth until their separate identity disappears. If one cannot achieve this total immersion and worldly memories persist, he advises consciously choosing to remember things that are pure and meaningful, such as the words of a Guru or images of the divine, to purify the mind.
