Makar Sankranti celebrates the transition of the Sun into Capricorn (Makara Rashi) and the commencement of Uttarayana (the six-month auspicious northward journey of the Sun). It brings hope, harvest, and spiritual renewal.
Uttarayana is considered the daytime of the Devas. Any charity, bath, or mantra chanting done on Makar Sankranti yields thousands of times more spiritual fruit.
On this day, the Sun God visits His son Shani (Lord of Capricorn). Despite their astrological differences, this festival commemorates harmony, forgiveness, and renewal of familial love and respect.
