...each living creature is said to be alive and to be the same individual — as for example someone is said to be the same person from when he is a child until he comes to be an old man. And yet, if he's called the same, that's despite the fact that he's never made up from the same things, but is always being renewed, and losing what he had before, whether it's hair, or flesh, or bones, or blood, in fact the whole body. And don't suppose that this is just true in the case of the body; in the case of the soul, too, its traits, habits, opinions, desires, pleasures, pains, fears — none of these things is ever the same in any individual, but some are coming into existence, others passing away.

Again, your being is never annihilated, but continues to develop its own existence in other ways. A portion of you has lived many lives upon this planet, but the "you" that you know is freshly here, and will never again encounter space and time in precisely the same way. The same applies to each life lived either before or after. Biologically you rest upon a heritage, however, and psychically the same applies. The soul, or this greater personage, does not simply send out an old self in new clothes time and time again, but each time a new, freshly-minted self that then develops and goes its own way. That self rides firmly, however, in the great flight of experience, and feels within itself all of those other fully unique versions that also fling their way into existence.

Nothing remains the same from one moment to the next, you can’t step into the same river twice. Life – evolution – the whole universe of space/time, matter/energy – existence itself – is essentially change.

"Nothing's ever the same," she said. "Be it a second later or a hundred years. It's always churning and roiling. And people change as much as oceans."

The past is never where you think you left it: you are not the same person you were yesterday

Everywhere, people show a face that is new, but at the same time basically the same. People are a mass of feelings, inclinations and ambitions, fluctuating between triumphs and defeats, despair and hope. Each is created from the same material, with the same innate nature, descended from one human family tree. (p180)

“Will she be the same?”
The old woman guffawed, as if I had said the funniest thing in the universe. “Nothing’s ever the same,” she said. “Be it a second later or a hundred years. It’s always churning and roiling. And people change as much as oceans.”

A person isn't who they are during the last conversation you had with them - they're who they've been throughout your whole relationship.

The only thing constant in life is change

We deceive ourselves to be the same for our whole life, instead we are other every moment.

In every life there are events that reshape one's sense of existence. Afterward, all is different and the past is dimmed.

Only the blindness of habit convinces us that we continue to live in the same place, that we see the same landscape. In truth, no place ever remains the same because light has no mind for repetition; it adores difference. Through its illuminations, it strives to suggest the silent depths that hide in the dark.

They are no longer the same because I myself am no longer the same. India always changes people, and I have been no exception.

You are under no obligation to remain the same person you were a year ago, a month ago, or even a day ago. You are here to create yourself, continuously.
