44. Then he should lead on the mind that has gained steadiness in respect of face and set it on the sky, i. e., on the form which is the cause of all and having left it and taken his stand on Me, the pure Brahman, he should cease to think of relation as the thinker and the thought.

44. V. The mind that has established itself (on that one member) should then be steadily devoted to the whole divine personality of excellence. In the next step even that intense concentration should be given up by him who is feasting on the realisation of Myself.

D. He should set on the complete personality of the Lord the mind that has established itself in realising the face. When he has his mind thus completely immersed in Me, he may stop the effort to concentrate the mind, for it is by itself in Him and he would not then naturally think of anything else. 45. He who has thus attained perfect concentration of mind sees himself in Me, the Antaryamin and also sees Me in himself like light united to light.
