By performing Vedic ritualistic activities, by giving money in charity and by undergoing austerity, one can temporarily become free from the reactions of sinful activities, but at the next moment he must again become engaged in sinful activities. For example, a person suffering from venereal disease on account of excessive indulgence in sex life has to undergo some severe pain in medical treatment, and he is then cured for the time being. But because he has not been able to remove the sex desire from his heart, he must again indulge in the same thing and become a victim of the same disease. So medical treatment may give temporary relief from the distress of such venereal disease, but unless one is trained to understand that sex life is abominable, it is impossible to be saved from such repeated distress. Similarly, the ritualistic performances, charity and austerity, which are recommended in the Vedas may temporarily stop one from acting in sinful ways, but as long as the heart is not clear, one will have to repeat sinful activities again and again.
Another example is given in the Śrīmad-Bhāgavatam of the elephant who enters into a lake and takes a bath very seriously, cleansing his body thoroughly. Then as soon as he comes onto shore he again takes some dust from the earth and throws it over his body. Similarly, a person who is not trained in Kṛṣṇa consciousness cannot become completely free from the desire for sinful activities. Neither the yoga process, nor philosophical speculations, nor fruitive activities can save one from the seeds of sinful desires. Only by being engaged in devotional service can this be done.
There is another evidence in the Fourth Canto of Śrīmad-Bhāgavatam, 22nd Chapter, 37th verse, wherein Sanat-kumāra says, "My dear King, the false ego of a human being is so strong that it keeps him in material existence as if tied up by a strong rope. Only the devotees can cut off the knot of this strong rope very easily, by engaging themselves in Kṛṣṇa consciousness. Others, who are not in Kṛṣṇa consciousness but are trying to become great mystics or great ritual-performers, cannot advance like the devotees. Therefore, it is the duty of everyone to engage himself in the activities of Kṛṣṇa consciousness in order to be freed from the tight knot of false ego and engagement in material activities."
This tight knot of false ego is due to ignorance. As long as one is ignorant about his identification, he is sure to act wrongly and thereby become entangled in material contamination. This ignorance of factual knowledge can also be dissipated by Kṛṣṇa consciousness, as is confirmed in the Padma Purāṇa as follows: "Pure devotional service in Kṛṣṇa consciousness is the highest enlightenment, and when such enlightenment is there, it is just like a blazing forest fire, killing all the inauspicious snakes of desire." The example is being given in this connection that when there is a forest fire the extensive blazing automatically kills all the snakes in the forest. There are many, many snakes on the ground of the forest, and when a fire takes place, it burns the dried foliage, and the snakes are immediately attacked. Animals who have four legs can flee from the fire or can at least try to flee, but the snakes are immediately killed. Similarly, the blazing fire of Kṛṣṇa consciousness is so strong that the snakes of ignorance are immediately killed. Kṛṣṇa Consciousness is All-Auspicious
Śrīla Rūpa Gosvāmī has given a definition of auspiciousness. He says that actual auspiciousness means welfare activities for all the people of the world. At the present moment groups of people are engaged in welfare activities in terms of society, community or nation. There is even an attempt in the form of the United Nations for world-help activity. But due to the shortcomings of limited national activities, such a general mass welfare program for the whole world is not practically possible. The Kṛṣṇa consciousness movement, however, is so nice that it can render the highest benefit to the entire human race. Everyone can be attracted by this movement, and everyone can feel the result. Therefore, Rūpa Gosvāmī and other learned scholars agree that a broad propaganda program for the Kṛṣṇa consciousness movement of devotional service all over the world is the highest humanitarian welfare activity.
