Om!
I would like to express my view on the profound subject – ADVAITA.
Advvaita (Non-duality) is the Ultimate Reality, there, where, only One exists but not two, is Advaita. All kinds of Yoga – Bhakti Yoga, Jnana Yoga, Raja Yoga, Hatha Yoga, Karma Yoga, Laya Yoga, etc., have this destination. So long two exists, Advaita can’t exist. In true Bhakti Yoga, also, so long a Bhakta (devotee) exists, the ultimate Bhakti can’t happen. Advait, verily, is the Ultimate Reality, is Sanatana Dharma, which is not started by any one, any rishi or any yogi, but is Forever, Unborn, Eternal.
Advaita State is beyond beyond all audios, videos, names, forms whatsoever. This is what is called the Chaturtha Padam of Om by Upanishad – अमात्रश्चतुर्थम् Amatraschaturtham (without any article, the 4th dimension of Om), शान्तम् Shantam (ultimate silence), शिवम् Shiwam (Auspicious), अद्वैतम् Adwaitam (Non-dual, Single, Solitude) and प्रपंचोपशमम् Prapanchopashamam (without names, forms, ideas, beliefs, physics).
That itself is called NIRVANA, which is Unborn, Unoriginated, Unformed and Uncreated. I speak of it as Ultimate Principle, Dharmakaya, Buddhahood, Nirvana, what matters it, they are only other names for ARYA PRAJNA, which is Sanatana Dharma. The same is called by Buddha, एस्स धम्मो सनन्तनो Essa dhammo sanantano / एष धर्मः सनातनः Esh dharmah sanatanah (This only is Eternal Dharma beyond Age and Time).
Om!
