18.48 So, one should not relinish one's works, understanding that they are natural, are easy to perform and not liable to negligence. Such thoughts coupled with the idea that there are imperfections in them should not lead you to abandon them. The meaning is that though one is fit for Jnana Yoga, one should perform Karma Yoga only. All enterprises, be they of Karma or Jnana, are indeed enveloped by imperfections, by pain, as fire by smoke. But still there is this difference:  Karma Yoga is easy and does not involve negligence, but Jnana Yoga is contrary to this.
