Now there is an apparently contradicting point made by Sri Adi Shankara, where he states that the Atman is the doer, on the grounds that the Vedas imply there is a direct benefit to someone (i.e. Atman) in carrying out the sacrifices. This seems, on first look to be a big contradiction to the teaching of the Gita i.e. Gunas and nature being the doer.
However there is an answer.
What is equally interesting is the fact that one is never apart from that nature. All is one, that Brahman. It is due to turiya (turya) that all has arisen. In addition to this Adi Shankara (I think) concludes that Atman is singular and not plural. In other words there is only one Atman, and that Atman is Brahman i.e. also nature. So the circle is complete. Yes nature is the doer, and turiya is not, but what is nature? Nature is Atman which is Brahman which is turiya. There is no duality just a different ways of explanation "until the penny drops".
Regarding the first part. Shankara says that all acts are on account of adhAsya. That atma is a doer is not mentioned anywhere by shankara. However, in stages, atma is the body, atma is the mind, and ultimaely atma is the atma. So, which atma is the actor, if any?
Actually there is a need to separate out the Turya from its effects. The source is the effects but the effects are not the source.
Regarding, the second part I agree. Whatever path one follows is immaterial since the Truth is indivisible one, its nature is indivisible one, and dukkha in the nature part is also one. So, by following any path, if dukkha is mitigated then one benefits since there are not many in truth.
