There are three kinds of devotees: The lower grade devotees, they have high regard for the Deity in the temple, but not very much regard for devotees or people in general. The second grade devotee takes compassion with innocent non-devotees. In that stage, he has got 4 kinds of vision: one is that he always keeps Krishna as the most Lovable Object, second is that he makes intimate friendship with his devotee God-brothers or any other devotees, third is that he takes compassion with innocent non-devotees, and tries to convince them about the importance of Krishna Consciousness, and fourth is that he does not take any serious interest for the atheist class of men. The first grade devotee, of course, sees everyone in relationship with Krishna and as such, he makes no distinction between a devotee or nondevotee. His vision is high grade, because he sees that everyone is engaged in Krishna’s service directly or indirectly. This position of high-grade devotee should never be imitated. It was possible only in Lord Caitanya or Lord Nityananda, or Haridasa Thakura. Thakura Haridasa was so powerful that he could convert even a harlot. But we should not try to imitate Haridasa Thakura or Lord Caitanya. Our position is in the second grade platform. We should not be satisfied remaining in the third grade platform. But we should try to elevate ourselves in the second grade platform. So far the first grade platform is concerned, it is not attained by our endeavor, but it is possible when we have full Grace of Krishna. It completely depends on the causeless Mercy of Krishna.
Subhadra is yogamaya. The spiritual energy is called yogamaya. And she has 16 different expansions. Out of these 16 expansions, Subhadra is one. The mahamaya of the material energy is also expansion of the energy of yogamaya; and both yogamaya and mahamaya are equally important to Krishna as much as any government department is equally important for functioning of the government. The police department may be horrible for the criminals, but to the government it is a department as good as university department. Similarly, mahamaya is horrible to the conditioned soul, but to the liberated soul, there is no fear of mahamaya, because he is protected by yogamaya. It is stated in the Bhagavad-gita when Krishna said the following: “I am not visible to everyone on account of being curtained by yogamaya.” So when a conditioned soul surrenders unto Krishna, the yogamaya winds up the curtain and Krishna is visible to the devotee.
