In Varanasi, in the Bada Ganesh temple, the deity has been covered with a quilt while his 'Moshak' has also been provided a woollen shawl.
At the Shiva temples, the "Shivaling" have been draped with a shawl.
Acharya Samir Upadhyaya said that once the idol is established in a temple with "Pran Pratishtha", then God is treated as a living entity and is, therefore, protected from the vagaries of weather.
In Ayodhya, Ram Lalla in the makeshift temple at the Ram Janmabhoomi site has been covered with a blanket and since the idol is kept in the open, a heat blower has also been installed there to keep the air warm.
Special care is being taken of Lord Krishna, especially in his childhood avatar known as "Laddoo Gopal". Tiny woollen sweaters and shawls are being used to cover the deity in various temples in Mathura and Vrindavan while bonfires are being lit for the devotees.
According to reports, several devotees make offerings of woollen clothes for the Idols in temples.
Several shops in these holy towns selling religious items, have also stocked up on woollen clothing for the deities.
Interestingly, some e-commerce sites have also started selling specially designer woollen clothes for the Gods.
