“All truly wise thoughts have been thought already thousands of times; but to make them truly ours, we must think them over again honestly, until they take root in our personal experience.”

“All intelligent thoughts have already been thought; what is necessary is only to try to think them again.”

“We are dealing with God's thoughts: we are obligated to take the greatest pains to understand them truly and to explain them clearly.”

“When someone dies, you don't get over it by forgetting; you get over it by remembering, and you are aware that no person is ever truly lost or gone once they have been in our life and loved us, as we have loved them.”

“As a single footstep will not make a path on the earth, so a single thought will not make a pathway in the mind. To make a deep physical path, we walk again and again. To make a deep mental path, we must think over and over the kind of thoughts we wish to dominate our lives.”

“I'll tell you truly: I value my thought and work terribly, but in essence - think about it - this whole world of ours is just a bit of mildew that grew over a tiny planet. And we think we can have something great - thoughts, deeds! They're all grains of sand”
