Biogeometry Signatures Mandalas Coloring Book

I have Biogeometry Signatures book where it is clearly mentioned that each Biosignature should be drawn from the correct side. The beginning of each signature has an arrow to point where we must start drawing it from.Dr.Ibrahim Karim also insists that these signatures should not be drawn in an haphazard way in one of his videos on youtube.Yet, this book on mandalas doesn't point out the direction & pattern. We are free to start wherever we wish; which is wrong!The book also feels very unprofessional as there is no index in it, no instructions, no user experiences / reviews, no suggestions.I was expecting colour suggestions as colours also affects human organs & emotions, however, colours not suggested in the book for mandalas even though the importance of colours is taught in Biogeometry.Very disappointed with the careless attitude of the author.
