Janeu - Kesariya

Janeyu in sacred saffron color for ritual ceremonies. The sacred Yajnopavitam is known by many names (varying by region and community), such as Janivaara, Jandhyam, Poita, Poonal, Janeu, Lagun, Yajnopavita, Yagyopavit, Yonya and Zunnar.
The janeu represent purity in thought, word and deed expected from the wearer.
Ancient texts refer to the wearing of the Janeu in three forms:
One is Upanayanam, where the Yajnopavitam is worn over the left shoulder and under the right arm. This is for Gods. 
The second is, where the Yajnopavitam is worn around the neck and over the chest. Nivita form is to be used during Rishi Tharpana, sexual intercourse, answering the calls of nature etc. and during ancestor worship/funeral rite.
The third, Prachinavaumltam is where the Yajnopavitam is worn above the right shoulder and under the left arm. This is for spirits and is used by men when performing the death ceremonies of an elder.

The strands of the sacred thread have symbolic meaning that varies by community and region. The sacred thread has three strands. A bachelor wears only one sacred thread whereas a married man wears two of them making it six strands. If the man has married and has fathered a child, he wears three, which makes it nine strands.
