No meditation, just hard work, and still they achieved life’s highest perfection

Srila Prabhupada in the Second Canto of the Srimad Bhagavatam describes that the residents of Vrindavan work so hard during the day that they sleep soundly at night.   He is also mentions that had very little time for meditation or other spiritual activities, but still their activity was the highest spiritually.  Why? Everything they did, they did for Krishna.  He writes,

The central point of activities was Kṛṣṇa, and as such, the so-called activities in the material world were saturated with spiritual potency. That is the advantage of the way of bhakti-yoga. One should discharge one’s duty on Lord Kṛṣṇa’s behalf, and all one’s actions will be saturated with Kṛṣṇa thought, the highest pattern of trance in spiritual realization. – Srimad Bhagavatam 2.7.31 purport
