SB 10.44.15

The ladies of Vraja are the most fortunate of women because, with their minds fully attached to Kṛṣṇa and their throats always choked up with tears, they constantly sing about Him while milking the cows, winnowing grain, churning butter, gathering cow dung for fuel, riding on swings, taking care of their crying babies, sprinkling the ground with water, cleaning their houses, and so on. By their exalted Kṛṣṇa consciousness they automatically acquire all desirable things. KB 10.44.15 “The gopīs are so fortunate that they can see and think of Kṛṣṇa twenty-four hours a day, beginning from their milking the cows or husking the paddy or churning the butter in the morning. While engaged in cleaning their houses and washing their floors, they are always absorbed in thought of Kṛṣṇa.” The gopīs give a perfect example of how one can execute Kṛṣṇa consciousness even while performing various types of material engagements. By constantly being absorbed in the thought of Kṛṣṇa, one cannot be affected by the contamination of material activities. The gopīs, therefore, are perfectly in trance, samādhi, the highest perfectional stage of mystic power. In the Bhagavad-gītā, it is confirmed that one who is constantly thinking of Kṛṣṇa is a first-class yogī among all kinds of yogīs.
