Mastering the mind : The starting point.
The starting point will be to do your practice most sincerely everyday morning and evening. See what you learn about mind everyday based on your experience, how can you work with what you learn today.
Go through the untethered soul and the voice of the knowledge. See what they are saying and learn through it.
You need to start writing what you know for sure and how you are planning to move forward from here.
You need to constantly engage in life moment by moment with better experiential understanding.
