Where do I find Steiner´s sayings and proverbs?

Is this Steiner´s mantra ?

 

In volume 40 of the complete works it´s on page 153

a complete register record of all sayings and mantras.

 

Most of the sayings are published in “Wahrspruchworte” GA 40 and in”Exercises for the Soul”, GA 267/268

 

The sayings for teachers are in GA 269
