Time and space are infinite. Grains of sand are countless. Atoms in the universe are innumerable, as are the stars and the galaxies. The same is true with life on this planet.
There is neither a beginning nor an end because everything is spherical. A sphere has no beginning and no end, no goal or direction. Truth has no direction, no goal. Truth itself is the goal, and truth is infinite.
Feeling and experiencing infinity within this finite body, living in timelessness within the time span of life, uncovering bliss within misery, this is what you are here for. When wisdom dawns, it gives rise to celebration. But in celebration you may lose your focus or awareness. The ancient rishis knew this, so to maintain awareness amidst the gaiety of celebration, they brought sacredness and puja to every event.
