Self Dedication

Self-dedication does not depend on the particular work you do, but on the spirit in which all work, of whatever kind it may be, is done. Any work done well and carefully as a sacrifice to the Divine, without desire or egoism, with equality of mind and calm tranquillity in good or bad fortune, for the sake of the Divine and not for the sake of any personal gain, reward or result, with the consciousness that it is the Divine Power to which all work belongs, is a means of self-dedication through Karma.
