All sensory enjoyments also bring suffering in their wake; therefore,
the wise ones do not indulge in the impermanent. In other words, the fleeting nature
of sensory experience always brings a sense of loss in its wake, and therefore
suffering follows. (5.22)
As fire is enveloped by smoke, as a mirror by dirt and as a fetus
remains enclosed in the womb, so is our true nature shrouded by desire. (3.38)
O son of Pritha, to that yogi of constant concentration and
single-minded attention, who remembers Me uninterruptedly and for long, I am
easy of attainment. (8.14)
By constantly thinking of sense objects, an attachment to
them is developed, which in turn creates desire. From desire anger comes, which
creates delusion, and consequently a person forgets oneself. Then one loses
discriminative power and destroys oneself. (2.62-3)
