Answer: Certainly. You can shout, curse, sing nice songs, or pray, do anything that you want. There is no significance to this; nothing influences the Creator.
You can be heard only when your desires are selflessly directed toward good through your friends‘ “spiritual weapons” directly to the Creator.
This is a language of sensations, a language of friendship, connection, love, and unity. It is not even necessary to clothe it in words and express it; it operates even this way. After all, the forces are what operate, not sound waves.
