Meditation means continuous remembering of the divine knowledge which yields the direct fruit here itself. Such a person gets a fruit in the upper world also. The only one Lord is the authority here and there also. Anybody blessed here will be blessed there also. If one is not blessed here he is not blessed in the upper world also. The grace of the Lord or the anger of the Lord is uniform here and there. One who is not blessed here cannot be blessed there. Thus the true knowledge blesses any person here and there. Meditation is continuous thinking of such knowledge and other interpretations are either useless or of little use.
