Periods of fast comprising a month are prescribed in all religions. The Hindus observe it in Maagha and Shravana months.

The name that is applied to the Festival celebrated with great joy by Keralites, Onam, is derived from the Samskrit, Shravana and Shronam, indicating the ascendant star of the day. The month too is Shravana. That word reminds people of the very first step in spiritual sadhana, the first of the famous nine, namely, listening to the Glory of God and imbibing joy therefrom.
