The pineal gland looks similar to a pine cone, hence the shared suffix. It serves an important function in transferring light waves into electro-magnetic signaling including the process we call thought, as well as dreams. In this way, it is associated as the 'third eye'.

It's classic import is hidden in plain sight with giant 'pinecones' as fountains or bannister or hearth decorations. They are everywhere.

Both the adrenal and pineal gland emit a fluid that has been used in rituals. This is the example in the use of the term 'walnut sauce', familiar to pedes.

Canaan Baalism was practiced by pirates, the first global intellegence network, and coded it as 'Long Pork'. Along the way, walnut sauce was discovered and what a long strange trip it's been ever since. See Johhny Depp in Pirates of the Caribbean and Fear and Loathing in Las Vegas for bragging examples from Hollyweird.
