Atman is a Hindu term for the transcendented mind. When it operates at the peak of unattachment (free of the body-brain and mind complex) one identifies oneself as mahatman. Spiritually atman and mahatman are not what is commonly said to be the soul. The mahatman is truth-consciousness personified. Hence the term satya-advaita vedanta or the Vedanta of Truth- Accommodation describes this transcendence of the mind. It is not a spirit from some God that descends into the mind as paramatman. It is the ascent of the mind to its highest possible potential. At this point knowledge has evaporated since there is no intellect. One does not want intellect, so perfect the state of being is in coping with one's moment by moment chores.
God is not required to function at this level. God in Satya-advaita lies dormant in one's psyche unless He/She decides to awaken the mind of a devotee steeped in bhakti. But God returns to the dormancy of His/Her abode once the person stands on his or her own two feet. So we are talking of Satya-advaita as theism of sorts, should I say qualified theism in view of the fact that the Satya-advaitist appreciates the existence of God but is unattached to the Supreme Being. Transcendentalism as practiced within Satya-advaita relates to the state of being that I have described above as mahatman.
Truth is considerably more important, and indeed immeasurably so than any other objective. Truth slays the demons int ones head and those outside if the correct process is enacted in an ever-changing Brahma-Nature. Truth-consciousness finds that path and slowly adopts the transcendentalist mode of the mind rooted in Satya-advaita.
