Here is the definition of Universal Mind from Wikipedia:
Universal mind may be defined as the nonlocal and atemporal hive mind of all aggregates, components, knowledges, constituents, relationships, personalities, entities, technologies, processes, and cycles of the Universe.
The nature of the Universal mind is omniscient, omnipotent, omnificent, and omnipresent.
It’s also the human nature. It’s believed that one has access to all knowledge, known and unknown. Through the Universal Mind, people have access to an infinite power; one then is able to tap into the limitless creativity of the One. All these attributes are present within one at all times in their potential form.
The notion of universal mind came into the Western Canon through the Pre-Socratic philosopher Anaxagoras, who arrived in Athens sometime after 480 BC. He taught that all things were created by Nous (Mind) and that Mind held the cosmos together and gave human beings a connection to the cosmos, or a pathway to the divine.
