Spiritual knowledge is a regular science. Just as two and two make four, similarly everything is clean and obvious here also and there is no scope for any kind of modification or change in that.
This version of Jap Ji, or the message of Guru Nanak, is sent out into the world in order to feed hungry souls, and quench their thirst for true knowledge of the higher life.
The "Jap Ji" deals with the practical aspect of the problem of spirituality more than with mere theory. Neither is it a mere work of literature. Earlier translations into English have tended to ignore this and have often failed to convey the true import of the original. In this rendering, an effort has been made to concentrate upon the message that the "Jap Ji" contains, rather than to indulge in a literary exercise. The study of this work will help all people, irrespective of the religion that they may profess.
