must be wise / jnani

 
Without being elevated to the position of a jnānī, or wise man, no one can stick to the principle of worshiping the Supreme Personality of Godhead.
Lord Krsna, however, has explained in the Gita that out of these four types of neophytes, the one who is wise is very dear to Him because a wise man, if he is attached to Krsna, is not seeking an exchange of material benefits. A wise man who becomes attached to Krsna does not want any return from Him, neither in the form of relieving distress, nor in gaining money. This means that from the very beginning his basic principle of attachment to Krsna is, more or less, love. Furthermore, due to his wisdom and study of sastras (scriptures), he can understand also that Krsna is the Supreme Personality of Godhead.    (More...)
It is confirmed in the Bhagavad-gita that after many, many births, when one becomes actually wise, he surrenders unto Vasudeva, knowing perfectly well that Krsna (Vasudeva) is the origin and cause of all causes. Therefore, he sticks to the lotus feet of Krsna and gradually develops love for Him. Although such a wise man is very dear to Krsna, the others are also accepted as very magnanimous because even though they are distressed or in need of money, they have come to Krsna for satisfaction. Thus they are accepted as liberal, broad-minded mahatmas.    (More...)
Without being elevated to the position of a jnani, or wise man, no one can stick to the principle of worshiping the Supreme Personality of Godhead. Others who are less intelligent, or those whose intelligence has been taken away by the spell of maya, are attached to different demigods, on account of the influence of the modes of nature. The wise man is he who has thoroughly understood that he is spirit soul and not simply a body. Because he realizes that he is spirit and that Krsna is the supreme spirit, he knows that his intimate relationship should be with Krsna, not with this body. The distressed and the man in want of money are in the material concept of life because distress and need of money are both in relationship with this body. One who is inquisitive may be a little above the distressed and the man in need of money, but still he is on the material platform. But a wise man who seeks Krsna knows perfectly well that he is spirit soul, or Brahman, and that Krsna is the supreme spirit soul, or Param-Brahman. He knows that the spirit soul, being subordinate and finite, should always dovetail himself with the infinite and supreme soul, Krsna. That is the relationship of the wise man with Krsna.    (More...)
It can be concluded that a person who is freed from the bodily concept of life is an eligible candidate for pure devotional service. It is also confirmed in the Bhagavad-gita that after Brahman realization, when one is freed from material anxieties and can see every living entity on an equal level, he is eligible to enter into devotional service.    (More...)
