“The great souls who engage in My devotional service attain Me, the Supreme Lord, and do not come back to this miserable material life, for they have attained the highest perfection.” Both while in the material body and after giving it up, a devotee attains the highest perfection in service to the Lord. As long as a devotee is in his material body, his probational activities in devotional service prepare him for being transferred to the Lord’s supreme abode. Only those who are one hundred percent engaged in devotional service can achieve this perfection.
