According to this view, the factors in human nature that have created the crisis in the world are not fatally connected with the instinctual nature of human beings and with the hardware of the human brain. Human beings are in a difficult and crucial stage of consciousness evolution and have the potential to reach eventually undreamt of levels of emotional, intellectual, and ethical development. In ancient times, this was dramatically expressed by the Neoplatonist Plotinus, who described mankind as poised midway between the gods and the beasts. Modern versions of the same idea can be found in the writings of Sri Aurobindo, Teilhard de Chardin, Gopi Krishna, and Ken Wilber.
Transpersonal psychology does more that just throw new light on the problem of the world crisis.
It also describes a wide spectrum of techniques by which we can accelerate consciousness evolution in ourselves and others. These range from ancient spiritual practices of the Oriental and Western mystical traditions to Jungian psychology, and clinical or laboratory methods of experimental psychiatry. The experiences of oneness with other people, nature, and the universe then lead to increased tolerance, capacity to love, development to deep ecological concerns, and a tendency to seek one's well-being in harmony with that of others. There has been a tendency among professionals to see the LSD state as a toxic psychosis and the experiences induced by the drug as a chemical fantasmagoria that has very little to do with how the mind functions under more ordinary circumstances. However, systematic clinical research with LSD and related psychedelics has shown that these drugs can best be understood as unspecific amplifiers of mental processes.
