3.21 Whatever 'an eminent man,' i.e., he, who is famous for his knowledge of all the scriptures and for his observance of the scriptural dictates, performs, others who have incomplete knowledge of the scriptures will also perform, following his example. With regard to any duty which is being performed with all its ancillaries by an eminent personage, the people with incomplete knowledge will do it with the same ancillaries. Therefore for the protection of the world, all acts that are appropriate to one's station and stage in life must always be performed  by an eminent man who is distinguished for his wisdom. Otherwise, the evil generated from the ruin of the large masses of the world (who neglect their duties by following his example), will bring him down, even if he were a follower of pure Jnana Yoga.
