Quote by Pedro Calderon de la Barca
"We all live in a dream. Life is just an illusion; a dream within a dream." ~ This philosophy was first introduced to me by The Matrix. Probing further into the movie revealed to me that this isn't a new age idea but a concept that predates Yugas. The flick's last soundtrack, Navras, whose lyrics are from the Bṛhadāraṇyaka Upanisad, made me see that the film was heavily inspired by the Bhagavad Gītā, the earliest known reference to this notion.
Accordingly to the Book, all universes and it's contained entities are just but a figment of Lord Vishnu's dream. He's in His deep slumber, where one second for Him is a yuga for mankind. With this as a reference frame, all astrological calulations such as the palnet orbiting times, etc. are mapped to our time system in Vedic Mathematics. Every breath He takes involves creation (inhale) and destruction (exhale) of worlds in His mind, where we are all just players in His dreams (Maya).
After this digging of the movie and the book, later in my life, once again I stumbled upon two poetic works which sings about this idea; in fact the lives of their authors had strikingly similarities (their life [short], death [distressful] and the ideas they wrote about [rebellious]). Subramanya Bharathi's நிற்பதுவே, நடப்பதுவே, பறப்பதுவே! (Questioning the World) and Edgar Allan Poe's A Dream Within a Dream.
This was shot on some beach in Goa, under the midday Sun. Darkness on the left (the shadow), Light on the right (the Sun), with man on the centre and the contrasting colours to his sides are symbolisms for Dualism.
