Wisdom is the sixth perfection, the final stage in the hierarchy of practices, and the most profound achievement for Buddhists. The other five practices can only reach a level of perfection when wisdom informs them thoroughly, altering their inner structure and deepest motivation. The difference between the ordinary practice of energetic striving and that same practice honed by wisdom is located in the quality of the conception of practice. Ordinary practice “perceives a basis,” that is, it operates as though the seeker, the act of seeking, and the energy sought are each separate and self-constituted entities. Ordinary practice “bases” itself on the naïve thought that all things are permanently identified by their “own-being.” This “common-sense” view fails to see what wisdom enables one to see, that there is no permanent “self-nature” separating the self from the energy that it seeks. …

Seeing all things wisely as “empty” of their “own-being” the bodhisattva begins to live differently in the world. Based on the vision that this perspective enables, this new way of living absorbs energy from the surrounding world and transmits quantities of energy that can be harnessed by others. Wisdom empowers that ability, in part by offering “freedom from the ideas of pleasant and unpleasant” and from all static dichotomies that keep us isolated and closed. Recognizing the contingent and ironic existence of all things, including one’s “self,” the bodhisattva is not overwhelmed by hardships. Although these hardships do not go away, their presence is “empty” of “own-being” and therefore open to a wide variety of conceptions and attitudes. Not bound to conventional self-understanding and not obligated to experience suffering and hardship as unbearable or insufferable, the bodhisattva attains levels of freedom, flexibility, and energy that are inconceivable in ordinary existence. It is in this light that the classic texts of Mahayana Buddhism envision the perfection of energy, and in this sense that they claim that “where there is energy, there is enlightenment.”
