The lowest of human beings can be elevated to the highest stage of devotional life if they are trained by the bona fide spiritual master well versed in the transcendental loving service of the Lord.
SB 2.9.36, Purport: The lowest of human beings can be elevated to the highest stage of devotional life if they are
trained by the bona fide spiritual master well versed in the transcendental loving service of the Lord. If the lowest can be so elevated, then what to speak of the highest, who are well versed in the Vedic knowledge? The conclusion is that devotional service to the Lord is open for all, regardless of who they are. That is the confirmation of its application for all kinds of performers of the service.
Therefore the devotional service of the Lord with perfect knowledge through the training of a bona fide spiritual master is advised for everyone, even if one happens not to be a human being. This is confirmed in the Garuḍa Purāṇa as follows:
- kīṭa-pakṣi-mṛgāṇāṁ ca
- harau sannyasta-cetasām
- ūrdhvām eva gatiṁ manye
- kiṁ punar jñānināṁ nṛṇām
"Even the worms, birds and beasts are assured of elevation to the highest perfectional life if they are completely surrendered to the transcendental loving service of the Lord, so what to speak of the philosophers amongst the human beings?"
