Lord Śiva is described in the Brahma-saṁhitā to be like curd or yogurt. Curd is not different from milk. Since milk is transformed into curd, in one sense curd is also milk. Similarly, Lord Śiva is in one sense the Supreme Personality of Godhead, but in another sense he is not, just as curd is milk although we have to distinguish between the two.

Material activities for sense gratification are the cause of material bondage, whereas the very same activities for the satisfaction of Kṛṣṇa are the cause of liberation. How the same activity can be the cause of bondage and liberation can be explained as follows. One may get indigestion due to eating too many milk preparations—condensed milk, sweet rice, and so on. But even though there is indigestion or diarrhea, another milk preparation—yogurt mixed with black pepper and salt—will immediately cure these maladies. In other words, one milk preparation can cause indigestion and diarrhea, and another milk preparation can cure them.

The miserable conditions of this material world can be corrected by a sufficient supply of milk, yogurt, honey, ghee, molasses, food grains, ornaments, bedding, sitting places and so on. This is human civilization. Ample food grains can be produced through agricultural enterprises, and profuse supplies of milk, yogurt and ghee can be arranged through cow protection. Abundant honey can be obtained if the forests are protected. Unfortunately, in modern civilization, men are busy killing the cows that are the source of yogurt, milk and ghee, they are cutting down all the trees that supply honey, and they are opening factories to manufacture nuts, bolts, automobiles and wine instead of engaging in agriculture. How can the people be happy? They must suffer from all the misery of materialism. Their bodies become wrinkled and gradually deteriorate until they become almost like dwarves, and a bad odor emanates from their bodies because of unclean perspiration resulting from eating all kinds of nasty things. This is not human civilization. If people actually want happiness in this life and want to prepare for the best in the next life, they must adopt a Vedic civilization.

Cāturmāsya should be observed by all sections of the population. It does not matter whether one is a gṛhastha or a sannyāsī. The observance is obligatory for all āśramas. The real purpose behind the vow taken during these four months is to minimize the quantity of sense gratification. This is not very difficult. In the month of Śrāvaṇa one should not eat spinach, in the month of Bhādra one should not eat yogurt, and in the month of Āśvina one should not drink milk. One should not eat fish or other nonvegetarian food during the month of Kārtika. A nonvegetarian diet means fish and meat. Similarly, masūra dhal and urad dhal are also considered nonvegetarian. These two dhals contain a great amount of protein, and food rich in protein is considered nonvegetarian. On the whole, during the four-month period of Cāturmāsya one should practice giving up all food intended for sense enjoyment.
