In the Samyutta Nikaya, the Buddha talked about the "Aryan silence". The Aryan silence is "a state of internal calm of heart, concentrated on its object, free from discursive thought and investigation, born of mental balance, a state of zest and ease." This is what the Buddha called the "second trance" which is "an interior tranquilization and intentness of thoughts, and is produced by concentration". In the Aryan silence, the mind is balanced and in control. The Buddha once advised his disciples who were engaged in pious talk, "It is fitting, brethren, for you, as clansmen thus to assemble and engage in pious talk. When ye meet together, brethren, ye should do one of two things: engage in pious talk or keep the Aryan silence."
