What did Gulliver do before reaching his majesty?

From the text:

When I had crept within four yards of the throne, I raised myself gently upon my knees, and then striking my forehead seven times against the ground, I pronounced the following words, as they had been taught me the night before, Inckpling gloffthrobb squut serummblhiop mlashnalt zwin tnodbalkuffh slhiophad gurdlubh asht. This is the compliment, established by the laws of the land, for all persons admitted to the king’s presence.
