Here the word used is sage. In reality it refers to a perfected individual , Guru. Someone Or a higher power fully capable of creating universes!
Such higher powers do exist. They have been described profusely in Yoga Vasistha.
Who knows we are one of the many people in a universe created by such a power
For such beings – our worldly problems of death, emptiness is nothing. They can rid us of it – provided we want to wake up and not want this world
Not wanting this world is not Easy. Just a very bad habit of ours
Such is the greatness, vastness, Joy of pure consciousness. Don’t waste your time with worldly desires. Go for something permanent
