Here is the trailer for "Samsara (2011)". It is the sequel to the silent masterpiece Baraka (1992) by Ron Fricke. "Samsara" is a Sanskrit word that refers to the cycle of birth, life, death, and rebirth. This is a silent masterpiece that shows the cycle of human existence on earth in all its forms and the impermanent transient nature of all things.
You can see the full film by buying it on Amazon.com or getting it from a torrent site. I just saw it and it was quite amazing and profound.
The official website describes the film, "Expanding on the themes they developed in Baraka (1992) and Chronos (1985), Samsara explores the wonders of our world from the mundane to the miraculous, looking into the unfathomable reaches of man’s spirituality and the human experience. Neither a traditional documentary nor a travelogue, Samsara takes the form of a nonverbal, guided meditation."
