Every thought has a corresponding physical manifestation that is clearly apparent in your life experience to the extent to which you have thought each thought. Every physical object you come across is the physical form of a thought you have thought and the degree to which it is apparent in your life experience is defined by the extent to which you have thought the thought that matches it, a thought that makes you feel similarly to the way you feel as you give your attention to the physical object.
Also, the nature of thoughts defines the nature of their corresponding physical manifestations. If you are picturing a vague and uniform light in the form of a color for instance, your life experience will then be filled with experiences of a similar nature.
In this case, the object would be an aspect of your life experience that matches a vague sense of a colored light. For example, the object could be physical light if you were picturing the amber light of the sun which would come in the form of experiences involving sunlight or an artificial light source. If you were thinking additional thoughts, such as thoughts of wealth, their corresponding physical manifestation may come in the form of money, a bank, a building, etc.
You can use the physical manifestation of a thought to harmonize with the vibrational frequency of your desires by focusing on the physical manifestation that appears after thinking thoughts about your desires too.
The giving of your attention to physical manifestations that correspond with thoughts of your desires will allow for you to align with the vibrational frequency of your desires to a greater extent and thus manifest matching experiences more extensively.
