The secret of karma yoga which is to perform actions without any fruitive desires is taught by Lord Krishna in the Bhagavad-Gita.
Swami VivekanandaEverything that has form, everything that is the result of combination, is evolved out of this Akasha.
Swami VivekanandaEven forgiveness, if weak and passive, is not true: fight is better. Forgive when you could bring legions of angels to the victory.
Swami VivekanandaHold to the idea, "I am not the mind, I see that I am thinking, I am watching my mind act," and each day the identification of yourself with thoughts and feelings will grow less, until at last you can entirely separate yourself from the mind and actually know it to be apart from yourself.
Swami Vivekananda
