One of the big questions is the "Do I really know?" Can it be proven right now?
Contrary to: Is it learned, aka appears in thought aka memory?
There is a lot of parroting going on. Something is read, we think we "know it", we think we "know" who we are, what kind of person we are and often simply repeat what someone else said about us and so on.
Does this mean challenging each thought? Yes. Each and every one.
Yes we say we experience others via our senses. We can feel, hear, taste, smell, see something.I am aware of them through the senses. From insects, birds, my cat, people.
Is in the felt, the heard, the tasted, the smelled, the seen included what it is?
Or is there just the feeling, the noise, the taste, the smell, the visual?
To focus on direct experiencing is a valuable tool. It is equally helpful to just notice the story which is woven around each and everything experienced.
Take for example 'my cat', you can check what the DE is, what senses are involved and you can also listen patiently to the accompanying thoughts.
Seeing the colour form thingy labeled cat you will find it is impossible to just "see".
Thoughts will appear immediately, labeling/describing what is seen. The name will be there.
Labeling of the action of the cat (it is sitting, yawning) - thoughts.
Stories about the cat - thoughts/memory.
How you feel about the cat - thoughts/memory or labelling of emotions.
See how there is a whole story around cat? It is even impossible to think the word cat, without a picture/thought image appearing immediately.
Thoughts are not the enemy. They are not to be dismissed and got rid off as soon as possible. There is nothing wrong with them at all, and they are not a hindrance to what you are seeking.
It is observing them how they do their weaving that lets you understand what is or what isn't.
Try observing merely observing thoughts and check with DE to see what is really there compared to what is pure and only thought content.
Start with sitting in front of your cat and allow everything to appear, sense intake, feelings like warmth in your chest, thoughts.
Find out how colour/form becomes cat and how cat is turned into 'my cat'.
Play around and do it lightly, like a child investigates something, no idea what it is, no plan what it should be and just being open to whatever result comes up.
You can do it with lots of other things. How does colour/form become car? How does a sound becomes bird song? Play.
