In plain words
Forgetting the Self, one takes the body for oneself and passes through births without number. At the end, to know the Self and to be the Self: see this as nothing but waking from a dream of wandering through the world.
Word for word
Forgetting oneself, thinking the body itself to be oneself, taking births without number, at the end knowing oneself and becoming oneself: see it as waking from the dream of wandering in the world.
