Sadaachar literally means good, noble conduct. Its heart is very simple: the behaviour that hurts me when done to me—let me never do to others. The one who keeps this rule truly becomes a person of right conduct. Good conduct is the real ornament of human life; it is the foundation and fragrance of character.
Its roots are truth, purity and self-restraint; its branches are humility, compassion, forgiveness, sweet speech, patience, cleanliness, honesty, freedom from anger, greed and deceit; its fruits are health, peace, respect and long life. A truly moral person does not carry crookedness even towards those who oppose him; the habit of honesty and goodness becomes natural and sweet.
Right conduct begins in thought. Let there be no crooked intention, no harsh or bitter words, no slander or deception. Keep the vow that speech shall be truthful, gentle, useful and timely. In the mind let clean streams of good will rise; let us practise the habit of blessing. The morning prayer of the wise is this: “O mind, rise with auspicious thoughts. May my day start with a pure intention and end with the satisfaction of good deeds.”
From such resolve springs a life of restraint: control over the senses, cheerful contentment, respect for elders and kindness to the weak, gratitude for help received, and a readiness to forgive. One who keeps these habits sees the world steadily: he avoids quarrel, lessens faults and multiplies virtues wherever he goes.
The disciplined person is not dry; his discipline blossoms as compassion. He does not become sharp-tongued or cruel in the name of righteousness. He refuses to insult, to mock, or to pierce with stinging sarcasm. Instead he prefers the noble habit of sweet speech. Politeness and gentleness do not make one weak; they reveal inner strength.
As fragrance spreads from a flower without effort, so goodness spreads from conduct. A heart softened by compassion becomes fertile for virtue; harshness scorches even one’s own merit. Therefore let the sweetness of speech, the habit of praise for others’ goodness, and the refusal to nurse resentment become our daily discipline.
Right conduct is not only a moral ornament; it is the secret of sound body and steady mind. Anger, lust, greed, jealousy and deceit are poisons; they disturb digestion, cloud sleep and breed disease. Calmness, contentment, cleanliness, self-control and truthful speech strengthen the nerves, deepen the breath and make the heart light.
Classical Ayurveda praises sadaachar among the true promoters of longevity. A person who observes the restraints and disciplines of right living is protected from many disorders; his face becomes bright, his senses clear, his mind quiet and creative. He moves through the world like a lamp that gives light yet burns no one.
One who lives by right conduct gains a victory without enmity. He walks a straight path even among crooked ways. His home becomes a place of trust; his community receives his presence as a blessing. Such a person is fearless in conscience and restful in sleep. When the lamp of life burns low, he is not seized by panic; he has already befriended the light.
Therefore let us choose the discipline that brightens, not the indulgence that darkens. If we want a new mind, new vigour and new youthfulness, let us return to the simple direction of sadaachar: truth with love, purity with compassion, restraint with cheerfulness, and sweet speech with service. This alone is the way to a long, luminous, beneficial life.
