Enlightenment is not about words and thoughts and concepts which can be doubted. Enlightenment is always here. By 'here' I don't mean this present space. Here is somewhere within where mind cannot reach. Presence is always here and you are always That. This here is not the opposite of 'there'. This here is nowhere, it is your Heart. When mind is still all comes back to the Heart. All the cosmos is but a speck in your Heart. Turn mind over into this 'here' and it is lost. Then only light, wisdom and love remain and This you are not different or apart from.
