What is a "path" in Buddhism?  For one,  it´s a generic term to describe the experience of increased insight and personal change when one does spiritual things (such as meditation or study).  It can be different for everyone.  

For example, one can have the following path: Step 1 - have a deep psychedelic non-dual experience.  Step 2 - figure out what this was, and how it corresponds to very old Buddhist concepts (actually, that´s my high-level "path"). 

And then, there are some systems with their own defined maps,  paths, stages, levels etc.   They can be long and complex. 

One of them is Daniel P Brown´s concept of "3 Maps".  He presented it, for example, in his famous "Sacred Sundays" interview.  It is very much steeped in his 50 years of practice and experience as a therapist, meditation teacher, and translator of Buddhist works.  It´s probably very cryptic for the uninitiated! So may be the descriptions of the individual boxes shown when you click on them. 

The diagram you see here is not to be understood as a strictly sequential road map of his teachings.  One has to understand it as high-level mappings of various concepts and practices into some sort of ascending order. 

In his Level 1 retreat, Daniel P Brown taught everything corresponding to the first map.  

However, many elements of the second path were already present as teaching material, for example, metacognitive awareness (2nd map) or self-liberation (3rd map). 

The subsequent retreat levels would then deepen those elements and introduce new ones. 

Anyway, this is one example if a "map" concept. There are others, or at least variants. Daniel P Brown, from his first writings, had tried to synthesise different maps into one overarching concept. This was described in his dissertation and in the book he co-wrote with Ken Wilber, "Transformations of Consciousness".
