The main goal of observing Caturmasya is to decrease attachment to material things and to increase devotion to Krishna. Srila Prabhupada writes in Caitanya Caritamrta, “Caturmasya should be observed by all sections of the population. It does not matter whether one is a grihasta or a sanyasi. The observation is obligatory to all ashramas.” He further explains how to observe the vow: “This is not very difficult. In the month of Sravana one should not eat spinach (green leafy vegetables of the nature), in the month of Bhadra one should not eat yogurt (yogurt used as binding agent for cake is allowed), and in the month of Asvina one should not drink milk (milk sweets, milk by-products are fine).
