Prabhupāda: "The path followed by pure devotees, who are well behaved and fully endowed with the best qualifications, is certainly the most auspicious path in this material world. It is free from fear, and it is authorized by the śāstras."
So this is the summarization of our Kṛṣṇa consciousness movement, that the path followed by pure devotees. Pure devotees means who has no material desire. That is pure devotee. Anyābhilāṣitā-śūnyam (Bhakti-rasāmṛta-sindhu 1.1.11). Śūnya means zero, one who has made all material desires zero. That is the way. In the Buddha philosophy it is called nirvāṇa. Nirvāṇa means make zero, śūnyavādi. But we cannot remain in the śūnya. That is not possible. Śūnyavādī-nirvāṇa means to give up material desires. It is not possible to give up desires. That is not possible. To give up desires means I am dead body, a stone. If I have got life, if I am not a stone, there must be desires. So where is the living entity who has no desires? That is not possible. If we kill somebody to make him desireless, that "If you are killed, then there will be no more desire," no, the desire will continue in the subtle body. Even one is finished, this material body . . . Sometimes they commit suicide out of frustration, that "This desire is not fulfilled. Let me commit suicide." No. That is ignorance. Desires continue in the subtle body—mind, intelligence and ego. And to fulfill the desire, Kṛṣṇa will give you another body. If we make a desire, it must be fulfilled, and Kṛṣṇa will give you facilities. Bhrāmayan sarva-bhūtāni yantrārūḍhāni māyayā (BG 18.61). Desire is so strong. So how to make it zero? That is not possible. To make it zero means no more material desire. That is to make zero material desires. Sarvopādhi-vinirmuktam (CC Madhya 19.170).
