The secret of karma yoga which is to perform actions without any fruitive desires is taught by Lord Krishna in the Bhagavad-Gita.
Swami VivekanandaAlways keep the mind cheerful. Everyone will die once. Cowards suffer the pangs of death again and again, solely due to the fear in their own minds.
Swami VivekanandaEducation is not filling the mind with a lot of facts. Perfecting the instrument and getting complete mastery of my own mind [is the ideal of education].
Swami Vivekananda
