I am perfectly Brahman
I am perfectly Brahman: who is there to judge me!
As to who said that, it is Purushouttama (Self) whose atman=Brahman. The person is already 'dead' in Samadhi. It is way past knowledge. So there is sothing to question in Self.
I am the Reality, I am the Truth, I am the eternal source and cause of Creation: Aham Brahmasmi.
One does Dharma so long as one is within a mind in consciousness. Once one leaves the mind as an entity of the past there is no Dharma or karma. There is only the dawning of truth.
Truth is the manifestation of Reality, the ultimate and absolute Reality being Brahman: get with It.
Advaita to me means living in all stages and levels of reality treating all the different aspects as one single reality: this being is termed Vishista-advaita Vedanta.
