To know what you know and what you do not know, that is true knowledge.
Silence is a true friend who never betrays.
To know that one knows what one knows, and to know that one doesn't know what one doesn't know, there lies true wisdom.
Love others as you would love yourself, judge others as you would judge yourself, cherish others as you would cherish yourself. When you wish for others as you wish for yourself and when you protect others as you would protect yourself, that's when you can say it's true love.
Silence is the true friend that never betrays.
True wisdom is knowing what you don't know
True knowledge is when one knows the limitations of one's knowledge.
