My son, there is no rest for me. That which Sri Ramakrishna called "Kali" took possession of my body and soul three or four days before his passing away. That makes me work and work and never lets me keep still or look to my personal comfort.
If any human being earnestly desire to push on to new discoveries instead of just retaining and using the old; to win victories over Nature as a worker rather than over hostile critics as a disputant; to attain, in fact, clear and demonstrative knowlegde instead of attractive and probable theory; we invite him as a true son of Science to join our ranks.

When the Son on the Cross promises paradise in his company to the good thief, when he promises the future feast in Heaven to the Apostles, when he speaks of the kingdom of the Father, he is always pointing toward eternity. However brief and close to the earth his words sound, they echo throughout infinite eternity and permeate the faith of his followers with their eternal content. He knows what he speaks of, what he brings with him and what he promises; and he can convey it to those who know it not. The very words he uses are designed to awaken in them a new sense: the sense of the eternal.
