The brahmanas, ksatriyas, vaisyas and sudras, along with the brahmacaris, grhasthas, vanaprasthas and sannyasis, are the members of the eight divisions of varnas and asramas, and they have their respective duties to perform for the satisfaction of the Supreme Personality of Godhead. When such activities are performed and the results are offered to the Supreme Lord, they are called karmarpanam, duties performed for the satisfaction of the Lord. If there is any inebriety or fault, it is atoned for by this offering process. But if this offering process is in the mode of goodness rather than in pure devotion, then the interest is different. The four asramas and the four varnas act for some benefit in accordance with their personal interests. Therefore such activities are in the mode of goodness; they cannot be counted in the category of pure devotion. Pure devotional service as described by Rupa Gosvami is free from all material desires. Anyabhilasita-sunyam [Madhya 19.167]. There can be no excuse for personal or material interest. Devotional activities should be transcendental to fruitive activities and empiric philosophical speculation. Pure devotional service is transcendental to all material qualities.
