There exists no greater megalomania than thinking that we are all alone in this cosmic ocean!

Window washers increase the vision in the windows of the buildings; wisdom quotes do the same thing in the eyes of the people!

You can do beautiful things with your friends; you can do beautiful things when you are all alone! In togetherness, listen to the music of the crowds; in solitude, listen to the music of the silence! Be neither afraid of the crowds, nor of the loneliness, because both are blessings!

If you see a lonely tree in the middle of nowhere, plant a tree next to it!

You mortal! You time-poor! Don't waste your scarce time to be patient!

Be as useful as a tree! Give life to others; be shelter to everyone; grant fruits to all! Be good like a tree!

Chickens are brave till the foxes come at night; mortals are courageous till the death comes at twilight.
