By Satsvarupa Dasa Goswami
LORD KRSNA HAS TWO ENERGIES, material and spiritual, but they can be used interchangeably if one knows how. Just as the same electricity can be used to heat or cool a building, so Krsna's energies can be used for different purposes according to the living entity's desire. That doesn't mean that the living entity can control Krsna's energies, only that he can use them. When a conditioned soul wishes to exploit the material nature, he contacts the material energy. When he no longer wishes to dominate or enjoy the material energy and instead uses it in Krsna's service, he contacts the spiritual energy. The living entity is called the "marginal potency" of God-he can go either way. The Bhagavad-gita (9.13) states: "Being marginal potency, as soon as the living entity is freed from the control of material nature he is put under the guidance of the spiritual nature." There are only two choices.
