Yagna - Mantra Chanting
The word mantra has two parts; man, which is the root of the Sanskrit word for the mind; and tra, which is the root of the word instrument. A mantra is, therefore, an instrument of the mind, a powerful sound or vibration that you can use to enter a deep state of meditation. A combination of certain codified sounds is a mantra. The correct chanting of mantras under the guidance of the Siddha (Guru) brings about the manifestation of thoughts and desires, and even of devs and devis. It is originated from Ved, which was written by Lord Brahma. The teachings of the Vedas consist of various mantric chants or hymns cognized by different seers or rishis from the cosmic mind. The body gets an effect from mantra chanting in a good way. It removes all the diseases from your body and keeps away your body from other negative energy.
