One attains the highest perfection by devotion to one's natural work. Listen to Me how one attains perfection while engaged in natural work.
Seers whose sins (or imperfections) are destroyed, whose doubts have been dispelled by knowledge, whose disciplined minds are attached with the Self, and who are engaged in the welfare of all beings attain Supreme Brahman.
A Karma-yogi whose mind is pure, whose mind and senses are under control, and who sees one and the same Self in all beings, is not bound (by Karma) though engaged in work.
