Thus, the field, as well as knowledge and the knowable, have been briefly stated. My devotee, knowing this, enters into My being.
He whohas controlled his mind and organs, who has the knowledge of the field and the knowable, and who fixes his mind on Me becomes one with Me. Thus the field described above (beginning with the great elements and ending with firmness, verses 5 and 6), knowledge described above (beginning with humility and ending with perception of the end of true knowledge in verses 7 to 11) and the knowable described in verses 12 to 17 -- these have briefly been stated. He who has singleminded devotion unto Me, who takes Me (Vaasudeva, the Supreme Lord, the omniscient, and the supreme Guru) as the Self of everything, he who thinks and feels that all that he sees, hears and touches is nothing but the Lord and he who has the right knowledge described above enters into My Being or attains release from birth and death.
