So, what's you favorite spiritual or religious or whatever quote? It can be from anybody as long as it touches upon the human spirit and its nature or gives some insight into our souls
Some of my favorites are

"You will not be punished for your hate, you will be punished by your hate" - Buddha

"The mind is everything. What you think you become" - Buddha

"People say that what we’re all seeking is a meaning for life. I think what we are seeking is an experience of being alive.. actually feeling the rapture of being alive." - Joseph Campbell

"To ask for a purely intellectual proof of the existence of God is like asking for the privilege of being able to see with your ears" - Meher Baba

“When you've understood this scripture, throw it away. If you can't understand this scripture, throw it away. I insist on your freedom.”
Jack Kerouac

Don't know if it count's as spiritual but this is one of my favorite quotes and one of the rare ones I try to learn by heart

I'm not a particularly spiritual or religious man but I love these two quotes:

“Whoever undertakes to set himself up as a judge of Truth and Knowledge is shipwrecked by the laughter of the gods”
and
"Great spirits have always encountered violent opposition from mediocre minds."

Those sound like the words of some deeply spiritual man, right? Well, not really, the one who said them was Albert Einstein

Quotes by scientists or atheist or whoever are just fine. Like I said, it doesn't need to be quotes by particularly spiritual people. A good quote has value no matter who said it, whether it was Buddha, Einstein or even someone anonymous tweeting something on the internet

I like that anonymous one "Don't regret the things you did in life, regret the things you didn't do" or however it goes.
I know it's cliche af and maybe not that deep but I feel for me it stands true on so many levels

Sometimes things are cliche for a reason... because they are true. What you wrote might be a cheap piece of wisdom but a lot of people find it to be very true. I know I've been living like that my whole adult life

I heard a cool one that immediately made me think of this thread

"We are not human beings having a spiritual experience. We are spiritual beings having a human experience"
Pierre Teilhard de Chardin

Oooh I like it! I like it a lot!
That's the kind of stuff I was hoping for
