vimukto mam upaisyasi
(The Most Confidential Knowledge, Text 28, Chapter 9)
Meaning: In this way you will be freed from bondage to work and its auspicious and inauspicious results. With your mind fixed on Me in this principle of renunciation , you will be liberated and come to Me.
**** A person who is thus always engaged in the service of the Lord or is always thinking and planning how to serve the Lord is to be considered completely liberated at present, and in the future his going back home, back to Godhead, is guaranteed.
