Cause of suffering (cont'd)

Those who do not know through Self-enquiry what is the truth of their natural state (Self) mistake the alien body to be "I" and see the world as different from themselves and hence suffer in delusion.

All other things except that ("I"), which shines as the one undeluded Existence-Consciousness-Bliss, are seen on account of the deceitful play of Maya.
-- (GVK 430)

Do not make any real and firm effort to annihilate the feeling "I am the body" (the ego). Know that the ego, "I am the body", is the sole cause of all samsara-dukkha (miseries of life)
