Tunnel vision, a mental flow state, is the process whereby an individual focuses on something present in their physical environment while thinking thoughts that are a vibrational match to it. This state of mind can be used to enhance the attraction between yourself and your desires.
By giving your attention to something within your immediate environment that is harmonized with your desires, while also thinking thoughts that are harmonized with your desires, you will then be focused on their pure vibrational frequency and the attraction between them and yourself will become greatly enhanced as a result.
