"Possibly. In the LSD state we may become conscious, in the words of Teilhard de Chardin, of the "entire complex of interhuman and intercosmic relations with an immediacy, an intimacy and a realism" that otherwise happen only in spontaneous ecstatic states and to a very few blessed people.
Agreement exists among spiritual leaders that the continuation of the present development, characterized by increasing industrialization and overpopulation, will result in the exhaustion of natural resources and destroy the ecological basis for mankind's existence on this planet. This trend to self-annihilation is reinforced by international politics based on "power trips" and the preparation of weapons of apocalyptic potential.
This development can be stopped only by a change in the materialistic attitude that has caused this development. This change can result only from insight into the deepest spiritual roots of life and existence, from comprehensive use of all forces of our intelligence and all resources of our knowledge.
This intellectual approach, supplemented by visionary experience, could produce an alteration of the consciousness of truth and reality that could be of evolutionary significance. LSD selectively and wisely used could be one means of supplementing intellectual with visionary insight and helping the prepared mind become conscious of a deeper reality."
