There is a mistake in the sketches that are included in Day 52. In these sketches, the second chakra is not where it should be, which is about in between of the two ovaries chakras, at the apex of the lower loop. Instead, a chakra has been drawn in the navel area, where there shouldn't be any.
The A-team will correct these pages as soon as possible. Meanwhile, I'll reproduce this information in other threads as well, hoping that as many people as possible will see it, in order to prevent potential confusion.
