An open crown chakra without the use of the third eye can actually be dangerous. Like an open trusting child who goes home with a stranger. Without the discernment and wisdom of the third eye, the opened crown chakra will promote trust in life but without discrimination, and thus blind faith can occur. You can see this pattern of blind faith in many kinds of people who follow specific religious doctrines without questioning the accuracy and appropriateness of the information.
The third eye is like a minerʼs light on the forehead, illuminating each individualʼs life path in the midst of the worldʼs confusion and complexity. The third eye is activated through focus and concentration.
