6.19 Yatha, as; a dipah, lamp; nivata-sthah, kept in a windless place; na ingate, does not flicker; sa upama, such is the simile-that with which something is compared is an upama (smile)-; smrta, thought of, by the knowers of Yoga who understand the movements of the mind; yoginah, for the yogi; yata-citasya, whose mind is under control; and yunjatah, who is engaged in; yogam, concentration; atmanah, on the Self, i.e. who is practising Self-absorption. By dint of practising Yoga thus, when the mind, comparable to a lamp in a windless place, becomes concentrated, then-
