There is, however, only one idea of duty which has been universally accepted by all mankind, of all ages and sects and countries, and that has been summed up in a Sanskrit aphorism thus: "Do not injure any being; not injuring any being is virtue, injuring any being is sin."
Swami VivekanandaThe power of meditation gets us everything. If you want to get power over nature, [you can have it through meditation]. It is through the power of meditation all scientific facts are discovered today. They study the subject and forget everything, their own identity and everything, and then the great fact comes like a flash.
Swami VivekanandaWhat we want now is an immense awakening of Rรขjasika energy, for the whole country is wrapped in the shroud of Tamas. The people of this land must be fed and clothed-must be awakened -must be made more fully active. Otherwise they will become inert, as inert as trees and stones. So, I say, eat large quantities of fish and meat, my boy!
Swami VivekanandaIf you intend to study the mind, you must have systematic training; you must practice to bring the mind under your control, to attain to that consciousness from which you will be able to study the mind and remain unmoved by any of its wild gyrations. Otherwise the facts observed will not be reliable; they will not apply to all people and therefore will not be truly facts or data at all.
Swami Vivekananda
