There are 2 levels of surrender: First level pertains to the transcendence of the “self”, second level require one to transcend the notion of there is a fixed “teaching”, to be followed towards the ultimate reality.
The second level of transcendence, requires a solid work in the first level before it can mean anything. Otherwise, one would run into the erroneous conclusion that one need not follow any teaching towards reality.
Therefore the Buddha said in this Sutra “法尚应舍，何况非法（even teachings should be surrendered, let alone non-teachings)“. First, surrender our attachments to the “self” and its various patterns (as will be explained in the rest of this sutra), then, surrender the attachment to the notion of a “fixed permanent teachings”, like what being presented in this Sutra. Such is the teaching of this section.

“Subhuti, the Tathagata knows and sees all; these living beings will thus acquire immeasurable merits.
Why? (Because) they will have wiped out false notions of an ego, a personality, a being and a life, of Dharma and Not-Dharma.
Why? (Because) if their minds grasp form (laksana), they will (still) cling to the notion of an ego, a personality, a being and a life.
If their minds grasp the Dharma, they will (still) cling to the notion of an ego, a personality, a being and a life. Why?
(Because) if their minds grasp the Not-Dharma, they will (still) cling to the notion of an ego, a personality, a being and a life.
Therefore, one should not grasp and hold on to the notion of Dharma as well as that of Not-Dharma.
“This is why, the Tathagata always said: Ye Bhiksus, should know that the Dharma I expound is likened to a raft. Even the Dharma should be cast aside; how much more so the Not-Dharma?
