One must be aware of all external actions, reactions, stimulations, surroundings (sight, sound, smell, touch) along with triggered thoughts, emotions, responses, judgements, yesterdays ideas, fantasizing, problem solving, to do's, must haves, desires etc... In short watch yourself in detail.
When one is totally aware of ones "outgoing" (external) movement, awareness of the "incoming" (internal) movement naturally, organically kicks in. Moving inward cannot take place until total awareness of ones "external presentation" is known without judging nor naming. This is why "seeking" falls short.
Like the tide, there is the movement of the outgoing, incoming and slack tide...all water, all one, and all are known within the outgoing and incoming movement of water.
What is being presented here is awaking to all movement so that you can be opened to the whole, the totality of life, nothing seperate...riding the Tide!
