The being also likes to emphasise that the vertical line is always viewed from above. The implications of this statement are that either the vertical line is as horizontal as the level lines, or that we perceive the line from above when it really is in front. Another reason for the being choosing to view the vertical line from above is the necessary emphasis that though a vertical line often implies hierarchy in our perspective, there really is none.
Examples of common gestures known from different culture levels:
A common gesture part of the Dog of Earth culture level is to sniff one another when greetings are exchanged with an emphasis on sniffing (and licking for that matter) the anus and genital area of the other person.
A common gesture part of the culture level of some peoples of Humans of Earth is to shake each others right hand with comfortably outstretched arms when greeting one another. A firm grip is often considered to be superior to a weak grip or no grip at all.
Not much is known about the Salllmahh of Gralllk_5 culture level as not much has been achieved in crossing the language barrier beyond a mostly mutual, peaceful understanding. But some have reported observing the Salllmahhs mirror each others alignment in greeting creating a small black hole rift just below their floating height. It is hard to say whether an actual alignment is taking place due to the highly irregular shape of the Salllmahhs.
