श्रीमद्वाल्मीकिरामायणे अरण्यकाण्डे षोडशस्सर्गः (४२व श्लोकमु)
Valmiki maharshi describes the lifestyle of SitaRamaLakshmanas during chilling winter season. Even in that biting cold, they woke up well before sunrise, reached the banks of Godavari and took bath in its ice-cold waters.
The above shloka says, “They then offered Tarpanams to PitruDevatas, and Devatas. They performed dhyaanam of Surya-Bhagavaan and other Devatas”.
This gem of a shloka illustrates the impeccable Aachaaram of Sita-Raama-Lakshmanas. Even in terrible winter, their morning schedule was un-affected. After bath in holy waters, they offered salutations to Gods as per the Shaastras. Valmiki maharshi describes the severity of cold by saying “even thirsty elephants are afraid of chilling waters and are not putting their trunks into the water”.
