The statement asserts that only the 'now' truly exists, and that you should focus your attention here. It suggests that past and future are not tangible realities but constructs of the mind.

From the Advaita Vedanta perspective, as taught by Ramana Maharshi, this 'present moment' is not merely a temporal point but the eternal Self, the pure consciousness that is unchanging. The perceived past and future are distortions arising from the ego's identification with thoughts and memories, which are themselves impermanent phenomena. The 'reality' of the present moment, therefore, is the direct experience of your true nature, the Atman, which is beyond the flux of time and mental activity. By abiding in this present awareness, you transcend the illusory world of duality and realize your non-dual existence. This is the core of Self-inquiry, the practice of asking 'Who am I?' to dissolve the ego and reveal the ever-present reality of Brahman.

In your life: Practice bringing your full attention to whatever you are doing right now, whether it's a simple task or a complex interaction, to anchor yourself in this ever-present reality.
