Archangel Uriel brings forth a brilliant crystalline energy flowing to the crown/head. This chakra is very strongly connected to cosmic consciousness.
An open seventh chakra denotes free flowing, open communication with the Spirit world. This also connotes great psychic/intuitive power and mediumship abilities. You are open to communicating with the Ascended Masters, Spirit beings and Light beings and may also access the Akashic records.
A blocked seventh chakra may cause fearfulness and unnecessary insecurity creating an intuitive stand still.
The best way to open the Crown chakra is visualizing white crystal light spinning the seventh chakra. Call upon Archangel Uriel to infuse it with light vibrations.
