One night Śrīmatī Rādhārāṇī was talking in a dream. "My dear Kṛṣṇa," She said. "Please do not play any more jokes on Me! Please stop! And please don't touch My garments either. Otherwise I shall inform the elderly persons, and I shall disclose all of Your naughty behavior." While She was talking like this in a dream, She suddenly awoke and saw some of Her superiors standing before Her. Thus Rādhārāṇī became ashamed and bowed Her head. This is an instance of alertness after awakening from sleep.
There is another instance of this. A messenger from Kṛṣṇa came to Śrīmatī Rādhārāṇī while She was sleeping, and Rādhārāṇī immediately awakened. Similarly, when Kṛṣṇa began to blow on His flute in the night, all of the gopīs, the beautiful daughters of the cowherd men, immediately got up from their sleep. There is a very beautiful comparison made in this connection: "The lotus flower is sometimes surrounded by white swans, and sometimes it is surrounded by black wasps who are collecting its honey. When there is a thundering in the sky, the swans go away, but the black wasps stay to enjoy the lotus flowers." The gopīs' sleeping condition is compared to the white swans, and the sound of Kṛṣṇa's flute is compared to a black wasp. When Kṛṣṇa's flute sounded, the white swans, which represent the sleeping condition of the gopīs, were immediately vanquished, and the black wasp sound of the flute began to enjoy the lotus flower of the gopīs' beauty.
