Advaita, being the non-dual reality, necessarily points to the essential truth in all religions. Paula Marvelly points out that: 'All religions and faiths contain an esoteric heart, a mystical belief that I AM is in fact synonymous with God.' (Ref. 353) As Gandhi said: 'If the same divinity constitutes the core of all individuals, they cannot but be equal. Further, divinity in one person cannot in any way be unjust to the same divinity in another person.' (Ref. 215) Sayings from the bible such as those of God to Moses ('I am that I am' ) or of Christ ('The kingdom of heaven is within you') express the fundamental truth of Advaita, the non-dual reality of Brahman.
There are two Sanskrit words that are used for 'path': marga, which also carries the sense of 'way, method or means' and upaya, that by which one reaches one's aim. In reality, it must be the case that we are already who we really are. Who else could we be? It is the illusory ego that believes that we are in some way limited and that wants to become eternally happy. Whilst this state of affairs continues, the search is doomed to failure. Paths and practices are therefore needed not in order that we may find something new but in order that we may uncover what is already here now. The reason why different paths are needed is that minds, bodies and egos function differently. All paths aim effectively to remove the obscuring effect of this ego. This can be done through the practices of devotion and surrender to a God, for example, in the case of bhakti yoga. It can also be achieved in simple day to day life of working, at whatever may be our particular job, by doing the work for its own sake and giving up any claim to the results, in the case of karma yoga. And it can be achieved by enquiry and reason, using the mind and intellect to appreciate the truth of the non-existence of the ego, in the case of jnana yoga.
