Why one should abstain from speaking abusive words

Shree Lalithambika Tripurasundari is considered as Mathrika devi, the Goddess of Sanskrit letters of Alphabets. In Sanskrit there are 36 consonants and 15 vowels.

Shree yantra is a combination of these letters written on the triangles and petals. There are 8 vasinyadi vak devis who rules the speech and the sanskrit letter of alphabets.

8 Vargas which are ruled by Devis Vashini, kameshwari, Modini, Vimala, Jayini, Sarveshwari and Kaulini are
A - Ka - Cha - Tha - Ta - Pa - Ya - Sa

The combination of the 15 Vowels (the Nityas) and the consonants (the 36 Tattvas) produces all sound, all mantra, all vibration, all word, and all music to the entire universe.

Trikaranshudhi is purity and unity of Thoughts, Speech & Actions. A human should have harmony of 3 shudis when communicate. Humans should abstain from speaking vikruti tatva or Tamasic and Rajasic words i.e abusive words for a reason.

People who are on japa tapa and upasana vidhis should abstain from speaking abusive and kalushita words as they say the pradhana devta herself or himself stays on their beeja or tongue and kantha the neck.

The vak devis rule the entire speech system and thus the amount of negative we use accumulates Vaakdosha. Man should abstain from negative words to attain mental peace and harmony. Using satva words help humans radiate a positive energy attracting all the positive from around.
