Aligning your energy

Moreover, his energies were never exhausted, not only because he was physically strong but because he followed the mainstream in himself. In this way he was unlike so many of the men and women of our time who live on the capital of their energies because they find themselves embattled against their natural selves. They do not earn new allowances of energy for themselves but merely exhaust the supply which nature had originally bestowed on them. Jung, on the contrary, seemed to generate more mental and spiritual energy for himself living, as it were, on interest and never touching the original investment of his nature. In this way both volume and value grew rapidly in an age of increasing inflation of mind and being until one almost wondered at times whether energy had not accomplished the impossible of spontaneous generation in him.
