As bodies die, the soul is continuously reborn in subsequent bodies and it carries all knowledge, according to R.D. Ratna Raju, former Head of Department of Physics, Andhra University.
Addressing a gathering at the AU Research Forum on Tuesday on the topic ‘quantum nature of soul’, he spoke on the concept and evolution of soul in Vedic and Western philosophies.
“The concept of soul can be traced to ‘Mandukya Upanishad’, the shortest of the Upanishads. It said that humans go through different states of being. The ‘Jagradavastha’ (state of waking consciousness), ‘Swapnavastha’ (in the realm of dreams), ‘Sushuptavastha’ (deep sleep) and ‘Turiya’ (when the soul departs the body),” he said.
Speaking about the idea of life after death, he said that after death of the physical body, some souls enter human forms and would be reborn while some take other forms of living beings, depending on ‘karma’ and ‘jnana’.
In the Western philosophy, the concept of soul evolved through the minds of the Greek philosophers – Socrates, Plato and Aristotle, Prof. Raju explained.
