If 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 VivekanandaRenunciation - non-resistance - non-destructiveness - are the ideals to be attained through less and less worldliness, less and less resistance, less and less destructiveness. Keep the ideal in view and work towards it. None can live in the world without resistance, without destruction, without desire. The world has not come to that state yet when the ideal can be realised in society.
Swami Vivekananda
