One of the main lessons in the BKs is soul consciousness. This less encourages deep self-reflexive inquiry into one's mind and one's heart. The life aim for BKs is, with the support of Raja Yoga meditation, to clean the self inside and out, and to cultivate the deepest levels of purity. Purity in the BKs is understood as a return to what is innate, true and original. A restoring of spiritual consciousness or 'soul consciousness'.
