ADVAITA, Monism, Atman, Brahman, Samadhi, Nirvana, Heaven, Kundalini... all simply mean: BLISS gets/is a hallucination called life (and then it “Awakens”) to be BLISS -- geza
actually nirvana is a sanskrit word which basically breaks down to mean "no" "variety" - how can there be bliss in the absence of variety?
answers and questions, particles and antiparticles there is no answer to your question or any other but there is an "ode to ONE"
