A wider of more altruistic attitude is very relevant in today's world. If we look at the situation from various angles, such as the complexity and inter-connectedness of the nature of modern existence, then we will gradually notice a change in our outlook, so that when we say 'others' and when we think of others, we will no longer dismiss them as something that is irrelevant to us. We will no longer feel indifferent.
Don't let yourself be weighed down by what other people think, because in a few years, in a few decades, or in a few centuries, that way of thinking will have changed. Live now what others will only live in the future.
The body and mind are continually changing, and are, in fact, only names of series of changeful phenomena, like rivers whose waters are in a constant state of flux, yet presenting the appearance of unbroken streams. Every particle in this body is continually changing; no one has the same body for many minutes together, and yet we think of it as the same body.
The lapse of ages changes all things - time, language, the earth, the bounds of the sea, the stars of the sky, and every thing about, around, and underneath man, except man himself.
