1. The Sacred Mother-Son Reunion at Renuka Lake
Every year from the tenth day of the bright lunar fortnight of Kartik through the sacred full moon of Kartik Purnima (celebrated across six continuous days and nights of Himalayan devotion, mountain palanquins, and lakeshore fairs in late November), the pine-clad valleys of Sirmaur district in southern Himachal Pradesh host one of North India's most venerated gatherings: the Renuka Ji Fair (Shri Renukaji Mela).
The sacred center of the pilgrimage is **Renuka Lake**—the largest natural lake in Himachal Pradesh, spanning an expansive circumference of 3,214 meters. Viewed from surrounding ridges, the serene emerald body of water bears an uncanny, natural physical resemblance to a **reclining, sleeping woman**. According to sacred Puranic lore, the lake is the personified form of **Mata Renuka**, wife of the great Vedic sage Jamadagni and mother of Lord Parashurama (the sixth avatar of Lord Vishnu). When tyrannical King Sahasrarjuna attacked the hermitage to steal the wish-fulfilling cow Kamadhenu and killed Sage Jamadagni, Mata Renuka jumped into the mountain waters to safeguard her chastity. Parashurama subsequently avenged his parents, destroyed the tyrannical kings, and revived his father through divine penance. Moved by her son's filial devotion, Mata Renuka promised to emerge from the lake depths once every year on Kartik Purnima to embrace him.
During the fair, Lord Parashurama's sacred silver-plated palanquin (**Palki**) is carried down from the ancient hilltop temple at **Jamu Peak** in a glorious ceremonial journey (*Shobha Yatra*) led by temple priests, brass Karnal trumpeters, and hill drummers. Upon reaching Dadahu on the banks of River Giri, the deity is greeted with royal state honors, proceeding to the lakeshore temple to reunite with his mother amidst the joyful cheers of over half a million pilgrims.
