Practical dharma, or rules of good behaviour (achara-dharma), relates to temporary matters concerning our problems and physical needs, to our passing relationships with the objective world. The very instrument of those rules, the human body, is not permanent, so how can then these rules be eternal? How can their nature be true? The Eternal cannot be expressed by the evanescent; light cannot be revealed from darkness. The Eternal emerges only from the Eternal; truth emanates only from truth. Therefore, follow the objective codes of dharma relating to worldly activities and daily life, with the full knowledge and consciousness of the inner basic Atma-dharma. Then only can the internal and external urges cooperate and yield the bliss of harmonious progress. If in your daily avocations, you translate the real values of eternal dharma into love-filled acts, then your duty to the inner reality, the Atma-dharma, is also fulfilled. Always build your living on the Atmic base; then, your spiritual progress is assured.
