First month of Chaturmasya begins
(fast from green leafy vegetables, for one month)
Chaturmasya is the four-month period, consisting of the rainy and autumn seasons in India, during which Vaishnavas perform austerities to invoke the mercy of Krishna. Traditionally, itinerant priests and preachers would take a break from their travels during this time. Nowadays, observers refrain from eating certain foods. The last month of Chaturmasya is known as Karttika, and is the holiest month of the year for Vaishnavas.
