Q: Gurudev, do Lord Brahma, Lord Vishnu and Lord Shiva really exist, or do we just awaken the qualities attributed to these Gods by doing Pooja?

Sri Sri Ravi Shankar: Lord Brahma, Lord Vishnu and Lord Shiva are present inside our own body as Shakti (the life force). Do not think that they are seated somewhere in the skies. So the qualities (attributed these Gods) will blossom by themselves as we continue to do meditation and satsang.
