देवशयनी एकादशी (१३ जुलाई) से लेकर कार्तिक शुक्ल एकादशी पर्यन्त धर्मपरायण तपस्वी
लोग चातुर्मास्य व्रतादि नियमों का पालन करेंगे ।

श्रावण, भाद्रपद, आश्विन और कार्तिकमासमें जलशायी जगदीश्वर भगवान्‌ का पूजन करे तथा नमकरहित अन्न भोजन करे। व्रत समाप्त होनेपर श्रेष्ठ ब्राह्मणको भक्तिपूर्वक दान दे। जौ, धान्य, शय्या, वस्त्र तथा सुवर्ण दक्षिणामें दे । जो मनुष्य एकाग्रचित हो इस प्रकार भलीभांति व्रतका पालन करता है, उसके ऊपर जगद्‍गुरु भगवान्‌ विष्णु बहुत प्रशन्न होते हैं।

Every year beginning with the 11th day of th moonlit period of Asadh (fourth month in the Hindu Calendar) until the 11th day of the moonlit period of Kartik (eight month of the Hindu calendar), i.e., a period of four months, it is believed that Hindu gods and goddesses are at rest. This period is reffered to as Chaturmas - four months.

Hindus do not perform auspicious ceremonies during Chaturmas.

Since gods and goddesses at rest can get enraged if disturbed during this period, it is customary not to organise auspicious occasions like weddings, moving into a new house, establishing a temple, organising a community prayer or other auspicious activities. These activities are renewed only after the gods and goddesses have completed their rest on the 11th day of kartik.

In the Padampuran, Shrimad Bhagwatpuran and other religious texts, this rest period is reffered to as yognidra, a term that describes the rest Vishnu took after annihilation of the world. This term is also used when Vishnu is in deep meditation and cannot be disturbed. The inability to be available to devotees is termed as sleep or rest.
