This is to all people who think wearing the things that indicate you are "Soubhagyavathi" or "Muttayide" or simply a married woman is a crap, traditional or old fashioned.
Let me tell you the scientific & spiritual reasons behind each.
Initially, there are 5 things in hinduism which indicate the woman is married.
1st- the Mangalasutra or commonly known as thali
2nd- the toe ring
3rd- the sindoor or kumkum
5th-the nose stead or nose ring
Mangalsutra is an auspicious thread tied by a groom to his bride on the day of marriage which is expected to be worn until her husband's death. This is the thread that binds a woman forever to her husband. This is mostly made in gold as an identifiable mark for married women. This too is believed to regularize a women's blood circulation. This is also said to control the body pressure levels to a maximum extent, as Indian women tend to work hard. Advised it should always be hidden. Just because of the constant friction of the metal gold touching the body portion directly, the effect will be more to gain the said benefits.
Toe ring: By wearing this in both feet, it is believed, that their Menstrual cycle course is regularized with even intervals. This gives good scope for conceiving to a married woman. Also it is said just because that particular nerve in the second finger from toe, also connects the uterus and passes through heart. Because of this, the constant friction caused while walking and doing all sorts of chores during a day, it revitalizes the productivity organs.Silver being a good conductor, it also absorbs the energy from the polar energies from the earth and passes it to the body, thus refreshing whole body system.
Nose ring or nose stead: Not an unfound myth. It is considered as a breath regularizing and some say it is just to eliminate the poison coming out while exhaling carbon.
Kumkum: The area in which the mark of the Kumkum is applied is between the eyebrows, called the “Ajna Chakra”. The tilak Sindoor or Bindi also represents our third eye (the spiritual eye) a concept closely related to Lord Shiva. The entire body emanates energy in the form of electromagnetic waves “ the forehead and the subtle spot between the eyebrows especially so. That is why worry generates heat and causes a headache. The tilak and pottu cools the forehead, protects us and prevents energy loss. Same resembles to the "Vibhuti" or 'Bhasma" applied on the forehead.
Bangles- Glass bangles have the Sattva component, Devi Principle and Chaitanya (Divine consciousness) in them. Due to the sound generated by the glass bangles, the negative energies back off.While the plastic bangles attracts negative energies. Glass bangles is said to increase the vital energy and the motor organs of the woman are protected, while plastic ones worn for fashion is said to decrease. With the help of these waves, the married woman is protected from the evil-eye and attacks of negative energies.
