When one’s cosmic play is done, one enters into nirvana. If one is a tired soul and wants to go permanently beyond the conflict, beyond the capacities of the cosmic forces, then nirvana is to be welcomed. Nirvana is the cessation of all earthly activities, the extinction of desires, suffering, bondage, limitation and death. In this state one goes beyond the conception of time and space. This world, earth, is the playground for the dance of the cosmic forces. But when one enters into nirvana, the cosmic forces yield to the ultimate highest Truth, and the Knower, the Known and the Knowledge or Wisdom are blended into one. At that time one becomes both the Knower and the Known.
If one does not have the experience of nirvana, he usually cannot know what illusion is. According to some spiritual teachers, the world is maya, an illusion. When one enters into nirvana, he realizes what illusion is. Nirvana is the static oneness with God. There, everything comes to an end in the static bliss. This bliss is unimaginable, unfathomable, indescribable. Beyond nirvana is the state of absolute oneness. This oneness is the dynamic oneness with God.
Nirvana is a very, very, very high state. However, it is not the highest state for the divine worker. If one wants to serve God here on earth, then he has to come back into the world again and again to serve the Supreme in humanity. If one wants to manifest the Supreme in the field of creation, then he has to work in the absolute dynamism of the Supreme, and not take rest in nirvana. This does not mean that the divine worker cannot have the experience of nirvana. The experience of nirvana is at the command of all God-realized souls. But permanent nirvana is for those who want to be satisfied with the static aspect of the supreme Brahman. If one wants to embody both the static and dynamic aspects of the Supreme, I wish to say that one should go beyond nirvana and enter into field of manifestation.
