Aranjana Charadu or Arainjaan Kayiru (Malayalam: അരഞ്ഞാണ ചരട് Tamil: ta:அரைஞாண் கயிறு Telugu:[1] మొలతాడు[2][3][4][5])[6][7][8] is a traditional custom prevalent in South India,[9] especially among the Hindu and Muslim communities.
It is a common belief that one should never remain nude from birth until death, and wearing the thread fulfills this requirement, nullifying potential negative impacts of nudity.
This practice is thought to enhance and preserve the vital energy associated with the Mooladhar Chakra, thereby preventing it from being wasted in uncontrolled sexual desires.
In ancient times, when scientific explanations were scarce, people depended on religious and cultural practices to maintain their well-being.
While it is primarily observed by the Hindu and Muslim communities, the practice goes beyond religious boundaries, with individuals from various backgrounds embracing this custom.
