There is also a form of concentration without any object of focus. In objectless samadhi, all thoughts and senses are in a latent form, although you are remain fully conscious. This means they are not active in focusing attention either in the unconscious level of mind, nor in the active, conscious level of mind.

It is important to understand that the objectlessness being addressed here is far deeper than simply quieting the noisy, churning conscious mind as one does when beginning meditation. Allowing a noisy mind to gradually calm itself is an important step, however it is important to remember that it is only a stepping stone to the unconscious.
