The way of life that is based on not harming any creatures, or causing the least harm when necessary, is the highest morality.

Tuladhara
Tuladhara is the righteous merchant of Varanasi celebrated in the Mahabharata, whose serene conversation with the sage Jajali reveals that the highest dharma is universal friendliness and non-violence toward all living beings, lived out in honest daily work.
Tuladhara is one of the most beloved teachers of dharma in the Mahabharata, a humble merchant of the holy city of Varanasi whose name has become a byword for the truth that genuine righteousness shines not from outward austerity alone but from a heart at peace with all beings. His name itself means "the bearer of the scales," the holder of the balance, and it is a fitting one: in his shop he weighed his goods with perfect fairness, and in his life he weighed every creature in the same even measure of compassion. Because he belongs to the timeless world of sacred narrative rather than to recorded history, his life is preserved not in dates or birthplaces but in the luminous dialogue that generations have lovingly carried forward. The story that immortalizes him is told in the Shanti Parva of the Mahabharata, the great book of peace and liberating wisdom. There lived a devoted sage named Jajali who undertook penances of extraordinary depth. He stood in serene stillness through wind and rain, given wholly to contemplation, until a pair of birds, taking his quiet form for a sheltering tree, built their nest among his locks. Out of tenderness Jajali remained gently unmoving until the eggs were laid, the young were hatched, fledged, and at last flew freely away. So great was this feat of patience and loving-kindness that Jajali felt he had drawn near to the summit of holiness. Then a gentle voice from the heavens lovingly invited him to look further still, telling him that there dwelt in Varanasi a tradesman named Tuladhara whose righteousness shone with a like radiance. Moved and curious, the sage journeyed to the city to seek out this merchant and share in the secret of his goodness. What Jajali found was an unassuming man keeping an open shop, selling spices, herbs, juices, and the simple wares of daily commerce. Tuladhara received the great ascetic with warmth and, knowing the cause of his coming, began to unfold a teaching of surpassing beauty. He explained that the morality he followed was nothing rare or hidden, but the most ancient and universal of paths: that mode of life "which consists of universal friendliness, and is fraught with beneficence to all creatures." The truly righteous person, he taught, regards all beings with the eye of equality, neither fearing others nor causing others to fear, harboring neither envy nor enmity, and treating every living thing as one treats oneself. This serene goodwill toward all, he said, is the foundation upon which all other virtues rest. At the heart of Tuladhara's teaching stands ahimsa, the principle of non-violence and forbearance toward every living being. He spoke of the gentleness that refuses to wound, the restraint that takes no more than is needful, and the reverence that recognizes the spark of life in the smallest creature. He praised the householder who lives by honest and harmless means, who deals justly, who keeps faith with all, and who performs his daily duties without greed, without deceit, and without the desire to dominate. In his own trade he embodied this teaching perfectly: he sold his goods at fair prices, treated every customer alike whether they brought him praise or blame, and conducted his work with such evenness of mind that no gain could elate him and no loss could disturb him. His was the wisdom of action purified of self—labor offered as a quiet sacrifice, performed with full devotion yet wholly free of attachment to its fruits. In this lies the enduring radiance of Tuladhara's example. Through him the Mahabharata gently widens the heart's expectations: the tradesman and the ascetic stand side by side as kindred souls, and each illumines the other. The lesson is luminous and liberating—that the path to the highest good is open to everyone, in every walk of life. The forest hermitage and the city marketplace alike can become holy ground; one need only live, wherever one is placed, with truthfulness, fairness, compassion, and an unshaken friendliness toward all that breathes. Sanctity, Tuladhara shows, is not a matter of outward setting but of the heart's orientation, and the marketplace tended with love can be as sacred a temple as any hermitage. The tradition relates that Jajali, hearing these words, was awakened to a deeper understanding of the dharma, his devotion blossoming into a wider and humbler love. The two—the merchant and the sage—are remembered together as companions on the road to the eternal good, each honoring the other's greatness. To this day Tuladhara is cherished as a beloved exemplar of "sukshma dharma," the subtle and inward righteousness that expresses itself through the faithful performance of everyday responsibilities toward others. He stands as a gentle, smiling witness that the great virtues of non-violence, honesty, and universal love are not the privilege of the few but the birthright of all, waiting to be lived out in the ordinary tasks of an ordinary day. In honoring him, the tradition honors the dignity of honest work and the boundless reach of a compassionate heart.
Wisdom
I understand morality, which is timeless and full of mysteries. It is the same ancient morality that is known to everyone, which is about being friendly to all and doing good for all creatures.
However, the person who truly understands the sacrifice is very rare.
Now, I will talk about the purpose of the means of sustenance.
