As an example, when we are listening to Dharma teachings, we think I exist, but actually the so-called “I” only exist within an instant. If we assume, in a succession of ten moments, that the fifth moment is “I,” then the first, second, third, and fourth moments constitute the past, while the sixth, seventh, eighth, ninth, and tenth moments are the future; the only moment in which I exist is the fifth moment. All things that are gone cannot exist – in any corner of the world, planet, or time frame; all things that have yet to come also cannot exist. Only the fifth moment remains, but this too will pass instantly. At which point we will think the sixth moment is “I,” then the seventh and eighth. When all the moments successively step into the present, we will continue to designate each moment as “I.”
