Consciousness is like a mirror and wiping its surface is not going to help clear the images away.
Recognize that consciousness is already pure and clean, that’s why it can be like a reflecting mirror.
Realise that consciousness is untaintable and incorruptible regardless of the content. Much like the mirror cannot be contaminated and defiled by the images it reflects.
And witness that you are pure incorruptible consciousness itself, in that instant when the mind is empty and the mirror reflects nothing.
After awakening to your true self, meditation will begin to make sense. You can start transforming some parts of your mind that send things to consciousness.
