There are lots of scientific reasons behind the use of Janoi, vein named Lohitika passing through the right ear regulates the flow of urine. So, when the person wears the sacred thread around his ear while passing urine it indirect helps in urinary system to regulate the urine flow, thus keeping urinary system and bladder healthy.

Covering the head and body with a cloth while urinating or defecating is necessary to prevent direct physical contact with Rajas-Tamas predominant waves. Janeu act as this cloth so after washing the hands, feet, and rinsing the mouth with water, take the janeu off the right ear. The spiritually reason is, the physical body above the navel is considered pure for performing religious rituals, while the portion below it is considered impure.

Many Deities live in the right ear; simply touching the right ear with the right hand presents the benefit of an Achaman which leads to internal purification. Hanging the Janeu on the sacred right ear prevents the induction of impurity. It also activate the Suryanadi which create protective cover of radiant waves around individual and prevent from Rajas and Tamas predominant activities such as urination and defecation.

Rules: Once Janeu is worn it is not supposed to be removed from one’s body and must hold on right ear during the urinating and defecating. New Janeu should be tied in case of break or lost. Individual do not allow touching dead bodies while wearing the Holy Thread on the body. In case if we come in contact with a dead body, one has to perform a process and change Janeu and observe fast for a day. Person must avoid any non vegetarian food and abusive language.

The thread is changed once a year on the occasion of Raksha Bandhan the full moon day in the month of Shravan. The Gayatri mantra is chanted before wearing the thread, the Gayatri mantra is as follows:

Upanayana ceremony is performed on boys on different age based on the Varna, 7 years for Brahmin varna, 13 years for Kshatriya varna, and 17 years for Vaishya varna. The secret of life through Brahmopadesam has been taught in ceremony. Second birth of individual happen when man seeks his spiritual identity; he symbolically accepts spiritual teacher as father and the Vedas as mother. Typically women do not wear the Janeu but girls can wear the threads around the neck according to Yajur Veda.
