Although Vṛkāsura continued his sacrifice for six days, he was unable to personally see Lord Śiva, which was his objective; he wanted to see him face to face and ask him for a benediction. Here is another contrast between a demons and devotees. A devotee is confident that whatever he offers to the Deity in full devotional service is accepted by the Lord, but a demon wants to see his worshipable deity face to face so that he can directly take the benediction. A devotee does not worship Viṣṇu or Lord Kṛṣṇa for any benediction. Therefore a devotee is called akāma, free of desire, and a nondevotee is called sarva-kāma, or desirous of everything. On the seventh day, the demon Vṛkāsura decided that he should cut off his head and offer it to satisfy Lord Śiva. Thus he took a bath in a nearby lake, and without drying his body and hair, he prepared to cut off his head. According to the Vedic system, an animal to be offered as a sacrifice has to be bathed first, and while the animal is wet it is sacrificed. When the demon was thus preparing to cut off his head, Lord Śiva became very compassionate. This compassion is a symptom of the quality of goodness. Lord Śiva is called tri-liṅga, “a mixture of the three material qualities.” Therefore his manifestation of the nature of compassion is a sign of the quality of goodness. This compassion, however, is present in every living entity. The compassion of Lord Śiva was aroused not because the demon was offering his flesh into the sacrificial fire but because he was about to commit suicide. This is natural compassion. Even if a common man sees someone preparing to commit suicide, he will try to save him. He does so automatically. There is no need to appeal to him. Therefore when Lord Śiva appeared from the fire to check the demon from suicide, it was not done as a very great favor to him.
Lord Śiva’s touch saved the demon from committing suicide; his bodily injuries immediately healed, and his body became as it was before. Then Lord Śiva told the demon, “My dear Vṛkāsura, you do not need to cut off your head. You may ask from me any benediction you like, and I shall fulfill your desire. I do not know why you wanted to cut off your head to satisfy me. I become satisfied even by an offering of a little water.” Actually, according to the Vedic process, the śiva-liṅga in the temple or the form of Lord Śiva in the temple is worshiped simply by offering Ganges water, because it is said that Lord Śiva is greatly satisfied when Ganges water is poured upon his head. Generally, devotees offer Ganges water and the leaves of the bilva tree, which are especially meant for offering to Lord Śiva and goddess Durgā. The fruit of this tree is also offered to Lord Śiva. Lord Śiva assured Vṛkāsura that he is satisfied by a very simple process of worship. Why then was he so eager to cut off his head, and why was he taking so much pain by cutting his body to pieces and offering it in the fire? There was no need of such severe penances. Anyway, out of compassion and sympathy, Lord Śiva prepared to give him any benediction he liked.
