In plain words
Leaning on a support is called duality; when duality is given up the Supreme dawns. Then the yogin is liberated while living, and when the body is laid down he is set free.
Word for word
Support is thus called duality; from giving up duality, the dawning of the Supreme. Liberated while living then is the yogin, and from laying down the body he is set free.
