When a devotee is engaged in the service of the Lord, he is said to have reached the attainment of yoga. The English equivalent of the word yoga is “linking up.” So actual linking up with Kṛṣṇa, the Supreme Personality of Godhead, begins when the devotee renders service unto Him. Devotees situated in the transcendental rasa of servitorship render their particular service whenever there is an opportunity. Sometimes they sit down in front of Kṛṣṇa to receive orders.
