The mind, which is nothing but a bundle of thoughts, is the window to perceive the world outside. But, the mind is not what perceives the world. It is only a window. The one who perceives the world is behind the window, so to speak. The consciousness "I am" is the cause for the perception of the world. No consciousness, no world. Simple.
When the mind is focused or turned outwards, it perceives the world of objects. In fact, objectification is through the mind only. The sense organs are the conduit for the mind to objectify the world outside. The mind creates the false identity of being a person, a "me". A false entity that believes itself to be the 'seer', the subject. Because of the belief in this false entity, one goes about thinking that it is "me" who is actually perceiving, seeing, hearing, thinking, talking, etc. Now, you may notice the word 'thinking' is in italics. That is because the false subject "me" is nothing but a thought. No thoughts, no "me". Yet, despite the absence of a "me", the perceiving goes on none the less. Only, there is no one (no "me") claiming to do the perceiving. This is obvious proof that the "me" is NOT the one who is doing the perceiving. The world appears to be, only as long as the mind is turned outward i.e. towards the sense objects.
To know who you really, really are, it is essential to turn the mind inwards. In this case, the mind is turned away from the sense objects to the source of the mind itself. The easiest way to do so is Self-Inquiry. On asking the question "Who am I?", the mind subsides into its source. The source is consciousness. When the mind is turned inwards, there is no mind left. Only consciousness prevails. The mind has submerged itself into its source, i.e. consciousness. There is just this Being, being Itself. Just being is bliss.
The path to bliss is simple. Just turn the mind inward to its Source.
