What is Vedanta: 

Vedanta is the Science of Self-Realization passed down for thousands of years. It's a language mirror that helps us understand and discriminate between our Real Self (Limitless Awareness-Existence-Bliss shining as ordinary consciousness) and the apparent world (in Sanskit, "mithya"). As there's only one Reality, we say reality is non-dual (Advaita). We're Reality now. Thus, no experience can solve our problem - our problem is ignorance. Vedanta is a valid means of knowledge, when wielded by a qualified teacher, to help remove ignorance of our true nature and free ourselves from the insecurity that comes from identifying with the body-mind-intellect. 

There is only ONE Vedanta. Only one “end of knowledge”. Advaita Vedanta explains the nature of this end of knowledge, which is the knowledge of the knower/Self, you.
