Ayurveda says that speech is a manifestation of prana.
Prana is life force, universal energy. The more prana, the healthier, more successful, more charismatic and harmonious the person. So, first of all, prana is consumed when a person speaks. Especially when he criticizes, condemns, claims or curses. According to statistics, 90% of all fights happen because we speak badly about someone. The most successful people are those who speak pleasantly and know how to control their speech.
The scriptures say that ascetic speech consists of the ability to speak the truth in pleasant words.
Karma is determined by our speech.
It is important to remember that if we criticize someone, we take on that person's negative karma and bad character traits. This is how the law of karma works. And we also take the qualities of the person we praise. Whoever criticizes us gives us his positive karma and takes away our bad.
Why do people who talk little and think achieve more? They don't lose energy. Another simple rule related to speech is that if we have done something good to someone and boasted about it to others, then at that moment we lose the positive karma and all the fruits of our piety that we earned in that act. Braggarts achieve little. Therefore, we should never boast of our achievements, because at this moment we lose all the fruits that we have earned in the past.
Thoughts determine speech, so it is important not to think badly of anyone. The more chaotic thoughts we have in our head, the more they appear on the tongue and the more chaotic our speech will be. He who thinks clearly speaks clearly. There is another level - learning to accept criticism. One of the qualities of the soul is that it is able to justify itself in any situation. The lower a person's level, the more excuses you hear from him.
