"That is why the importance of chinkon in Shinto has been emphasized repeatedly since ancient times. Chinkon is different from simple mental concentration or the quieting of the mind. Through the practice of chinkon one can actually break through the wall of other dimensions existing in their mind. When this happens, the other world will appear, and they will become aware of the worlds of spirit and Kami. Without this, people cannot approach Kami filled with reverence and awe, nor can they experience true faith with gratitude in their hearts and minds. However, the faith I am talking about here is not something that can simply be taught at college."
