The real state of samadhi is that in which we remain attached with Reality pure and simple, every moment, no matter if we are busy all the time with our worldly work and duties. It is known as samadhi, one of the highest attainments, and the very basis of nirvana[illuminated state]. Its merits cannot be described in words, but it can be realized by one who abides in it.
It is only when we break the wall of greatness and submit ourselves as humble, insignificant servants of the Master, of God, and only when we become nothing, subduing our tendencies and allowing him to take charge of our existence, that life will be truly enjoyable. That means total surrender.
