Somebody insults you and you feel anger. Don't miss this opportunity; try to understand why, why this anger. And don't make it a philosophical thing. Don't go to the library to consult about anger. Anger is happening to you -- it is an experience, a live experience. Focus your whole attention on it and try to understand why it is happening to you. It is not a philosophical problem. No Freud is to be consulted about it. There is no need! It is just foolish to consult somebody else while anger is happening to you. You can touch it. You can taste it. You will be burned by it.
We often confuse spiritual knowledge with spiritual attainment. Spirituality is not a matter of knowing scriptures and engaging in philosophical discussions. It is a matter of heart culture, of unmeasurable strength.
'Thou shalt not kill' does not apply to murder of one's own kind only, but to all living beings and this commandment was inscribed in the human breast long before it was proclaimed from Sinai.
Science is a match that man has just got alight. He thought he was in a room - in moments of devotion, a temple - and that his light would be reflected from and display walls inscribed with wonderful secrets and pillars carved with philosophical systems wrought into harmony. It is a curious sensation, now that the preliminary splutter is over and the flame burns up clear, to see his hands and just a glimpse of himself and the patch he stands on visible, and around him, in place of all that human comfort and beauty he anticipated - darkness still.
Philosophical knowledge is the knowledge gained by reason from concepts ; mathematical knowledge is the knowledge gained by reason from the construction of concepts.
