Once when Kṛṣṇa and His cowherd friends were enjoying friendly conversation, Kṛṣṇa began to address His associates in casual language. At that time Kṛṣṇa’s servant Patrī was also enjoying the conversation. But then, remembering his position of servitude, Patrī bowed down before his master, and with great respect and control, he stifled his smiling. This subdued smiling is an instance of concealment caused by a respectful attitude.
