Simply ask the mind ‘Is awareness present or not?’ is enough.
There’s no problem if you don’t see the awareness; just keep going. Don’t try to look for the awareness.
If you continue to practice this way – sometimes using the question ‘Is awareness present?’, when the mind has enough wisdom, it can recognize itself.
Trying to be aware of awareness is more difficult; it’s easier to approach that by asking ‘Is awareness present?’
If you can say that you continue to be aware, you are already aware of the awareness.
Sometimes yogis look for the answer in something extraordinary when in actual fact, they already know it.
