You might find that you're lost in thought. Remember that thoughts are simply thoughts. Emotions are simply emotions. They are appearances in consciousness. When a thought disappears, you don't disappear with it, and the same is for emotions. You're the witness of thoughts and emotions. Sit with yourself and turn your attention inwards, and ask yourself "Who is thinking these thoughts?". When the thought arises, use your attention to find where that thought comes from. Don't use words for this, as that's just thoughts trying to figure out thoughts, or mind trying to figure out mind. Simply sit with yourself and just watch your mind. Don't identify with it or fight or follow these thoughts, resisting or fighting them only makes them stronger. Just turn your attention inwards and stay like this for a bit. You will notice these thoughts arise and you're aware of them. YOU are aware of them. This awareness is consciousness, and since it is aware of plays of the mind - thoughts, judgements, imagination, memories. And emotions. This state cannot be sad, depressed, agitated, as these are things that can be perceived. You start seeing thoughts from a distance, as clouds just passing in the sky of consciousness. This is the true and natural human condition. Society's conditioning has made it so our minds are wildly out of control, constantly running around in circles, wanting this then that. Take a step back. Dwell in the stillness of the natural and fundamental awareness state we are as humans. There is no suffering here. Consciousness doesn't sleep, it is never tired.It is neither doing or undoing. It is simply rooted in the present and aware of mind, body, sensations, and the outside world. Practise coming into this state and use this as your form of mindfulness. This state has no shape or center, be careful of mind trying to give it a shape and location. Everything is appearing in consciousness, even your suffering. You'll find that when in this natural state, the suffering will quickly end. But realising this state might take some practice as you're probs so endorsed into believing you're the thinker of thoughts, etc. Take your time and start slow. Feel free to listen to the nearoscientist Sam Harris to do with more on this, or Mooji for a more spiritual take on it. Peace.
