4.28 Some Karma Yogins perform the sacrifice of material objects. Some worship the gods with materials honestly acired. Some practise charity, some engage themselves in sacrifices and in making oblations into the sacred fire. All these perform sacrifice with material objects. Some do the sacrifice of austerity by devoting themselves to Krcchra, Candrayana, fast, etc. Others perform the sacrifice of Yoga. Some devote themselves to making pilgrimages to sacred sanctuaries and holy places. Here the term Yoga means pilgrimages to sacred sancturaries and holy places as the context relates to aspects of Karma Yoga. Some are devoted to recitation of Vedic texts and some to learning their meaning. They are all devoted to the practice of self-control and of strict vows, i.e., they are men to steady resolution.
