Hindu Dharma considers the mangalsutra to be a soubhagyalankar (Soubhagya is marital status of a woman and alankar is ornament) of the woman. This ornament is to be placed around the bride’s neck by the groom at the time of marriage.
The person’s left channel (Nadi) is associated with the saviour (Tarak) energy, which is mainly 'action dominant' (Karmapradhan - an action that is done with a beneficial purpose like Protection of the Nation or Dharma), and this is also called the Moon Channel (Chandra-nadi). The right channel (Nadi) is associated with the destroyer energy.
