Quotes:Turiya Avastha

H. P. Blavatsky

Turîya Avasthâ. Almost a Nirvânic state in Samâdhi, which is itself a beatific state of the contemplative Yoga beyond this plane. A condition of the higher Triad, quite distinct (though still inseparable) from the conditions of Jagrat (waking), Svapna (dreaming), and Sushupti (sleeping).
