Flaw
Bhagavad-gita As It Is
BG Chapters 1 - 6
Sāṅkhya-yoga, or the analytical study of the nature of spirit and matter, is the subject matter for persons who are inclined to speculate and understand things by experimental knowledge and philosophy. The other class of men work in Kṛṣṇa consciousness, as it is explained in the 61st verse of the Second Chapter. The Lord has explained, also in the 39th verse, that by working by the principles of buddhi-yoga, or Kṛṣṇa consciousness, one can be relieved from the bonds of action; and, furthermore, there is no flaw in the process. The same principle is more clearly explained in the 61st verse—that this buddhi-yoga is to depend entirely on the Supreme (or more specifically, on Kṛṣṇa), and in this way all the senses can be brought under control very easily.
