Small changes:

Humility, tolerance, forgiveness and understanding constitute the secret of happiness.
Together with wisdom, they lead to success.

---Notes---
"Comprehension" has a limited meaning, like simply understanding an idea or a question on an examination
"Understanding" is a more fully human quality, of also seeing other people as they are and accepting them as they are

Wisdom does not seem to be specified here, the text seems to speak of wisdom in general

Other small stylistic points corrected

I agree, master!

Thanks.
I'll edit that.
