Para-Brahman is the all inclusive - he is the head from which all concepts including the alphabets emerge.[citation needed] The honey of all knowledge (i.e. the universal set of all concepts like mind, intellect, speech, alphabets, etc.) to denote this, a special term - not originating from alphabets - called OM is used.[citation needed] He is the fountainhead of all concepts but He Himself cannot be conceived. He is the universal conceiver, universal concept and all the means of concept. Apara-Brahman is the same Para Brahma but for human understanding thought of as universal mind cum universal intellect from which all human beings derive an iota as their mind, intellect etc.[citation needed]
