It is interesting to know you are on the Advaita Vedanta path, it is an interesting school. I have encountered a few anti-advaita perspectives and the term mayavada. It appears that Shankaras predecessors needed to first dismiss his philosophy in order to promote their own. I find ISKONs arguments to be the less convincing. Although I have the impression ISKON have brought good people happiness and value in their spiritual life. My interest lies in philosophy and Vedanta and not on discouraging those happy with their faith or religion.
An example of the argument against Shankara is clear from Bhagavad Gita As It IS. The part I quote is clear that it serves to change the readers opinion of others in order and justify their own argument later, here is an example of an a negation of Monism to justify their point of view.
Quote:
Yoga practice is more or less based on the principles of the Patanjali system. Some unauthorized commentators try to identify the individual soul with the Supersoul, and the monists think this to be liberation, but they do not understand the real purpose of the Patanjali system of yoga.
There is an acceptance of transcendental pleasure in the Patanjali system, but the monists do not accept this transcendental pleasure, out of fear of jeopardizing the theory of oneness. The duality of knowledge and knower is not accepted by the nondualist, but in this verse transcendental pleasure--realized through transcendental senses--is accepted. And this is corroborated by the Patanjali Muni, the famous exponent of the yoga system. The great sage declares in his Yoga-sutras: purusartha-sunyanam gunanam pratiprasavah kaivalyam svarupa-pratistha va citi-saktir iti.""
I am doubtful that a strong philosophical argument can base a convincing theology on the sentence: "Yoga practice is more or less based on Patanjali". It is like saying that despite Lord Krishna teaching Arjuna all the wisdom that the Bhagavad Gita holds, Lord Krishna was actually basing his Yoga practice "more or less" on Patanjali. It then becomes a debate on which degree Lord Krishna is basing His teaching on Patanjali. This distracts I feel from the truth itself that the Lord teaches. Also what is "more or less", surely if you don't know exactly how can you based your philosophy on a "more or less"? Unless the reader is happy to overlook that of course.
Well, once the reader accepts one or more negations of a predecessors philosophy, the question which arises is what then is the right way for me to go?. This is followed by our way of course is right! and so the aspriant becomes a devotee. I feel this isn't a way forward, at least not for me, I like good investigation and intellegient philosophy.
My point is to bring awareness into how philosophical argument can lead a spiritual aspirant into accepting this school of thought, almost on faith and rejection of other Archaryas. I personally feel each individuals commitement to a religion or spiritual path requires the individual to engage in more founded, traditional Self-investigation, discrimination and philosophy. I would not place my self in a situation which is founded on more or less statements or generalisations that monists have "not understand the real purpose of the Patanjali system of yoga." How can such generalisations be accepted so easily by so many?
