Our spontaneous reactions, however, are only the seeds of these higher qualities, not their substance. To acquire the capacity to sustain our practice of Dhamma, renunciation and compassion must be methodically cultivated, and this requires an ongoing process of reflection which transmutes our initial stirrings into full-fledged spiritual virtues. The framework within which this reflection is to be exercised is the teaching of the Four Noble Truths, which thus provides the common doctrinal matrix for both renunciation and compassion. Renunciation develops out of our innate urge to avoid suffering and pain. Thence the governing motive behind the act of renunciation is the longing for spiritual freedom, coupled with the recognition that self-purification is an inward task most easily accomplished when we distance ourselves from the outer circumstances that nourish our unwholesome tendencies.
Compassion develops out of our spontaneous feelings of sympathy with others.
However, as a spiritual virtue compassion cannot be equated with a sentimental effusion of emotion, nor does it necessarily imply a dictum to lose oneself in altruistic activity. Though compassion surely includes emotional empathy and often does express itself in action, it comes to full maturity only when guided by wisdom and tempered by detachment. Wisdom enables us to see beyond the adventitious misfortunes with which living beings may be temporarily afflicted to the deep and hidden dimensions of suffering inseparable from conditioned existence. As a profound and comprehensive understanding of the Four Noble Truths, wisdom discloses to us the wide range, diverse gradations, and subtle roots of the suffering to which our fellow beings are enmeshed, as well as the means to lead them to irreversible release from suffering. Thence the directives of spontaneous sympathy and mature compassion are often contradictory, and only the latter are fully trustworthy as guides to beneficent action effective in the highest degree.
