Acharya Prashant explains that the instruction in the Bhagavad Gita to 'remember Me at all times' is not a literal command to repeat a name, but a spiritual method to cleanse the mind. He points out the paradox that while scriptures urge us to remember the Supreme Truth, they also describe it as formless, nameless, and beyond the reach of the mind. Since the human mind is essentially a bundle of memories rooted in the body and the past, it is constantly filled with worldly thoughts and trivial concerns. The speaker clarifies that remembering the Truth is not the ultimate goal, as the finite mind cannot truly grasp the infinite; rather, it is a technique to displace the 'garbage' of worldly attachments.
