The marginal position of voidness between Brahmajyoti and the material world manifestation is the destination of the Buddhist philosophers. Therefore the voidness philosophy is worse than Impersonalist philosophy. This voidness philosophy is simply nirvana, or absence of material manifestation, but actually it is a material stand whereas Impersonalist monism is transcendental to material manifestation and voidness. Therefore the conception of Brahmajyoti is advanced realization than conception of nirvana. Nobody can be satisfied in void or Impersonalist philosophy; they are against the nature of the spirit soul. We understand from Vedanta philosophy that the spirit soul is by nature joyful. There is no joy in voidness or Impersonalism and because such imperfect philosophers do not know of the association of Krishna which is full of bliss and knowledge, they will fall down repeatedly into voidness and Impersonalism with the result that they cannot stay there and they fall down to the material atmosphere. In Bhagavad-gita it is said by the Lord that these people, void and Impersonalist philosophers, are in great trouble. If they are fortunate enough to meet a pure devotee of Krishna and if they are sincere in their search for the absolute truth, they will find Krishna Consciousness as the last resort of their philosophical researches. Try to help these bewildered philosophers by presentation of your nice Krishna Consciousness thesis which you have prepared, and I am sure Krishna will help you in all respects. Simply your sincerity of service is required and He will dictate from within you how to make your thesis. It will be a great service to the humanity, especially to the Western world.
Regarding Ba'hai philosophy: I have read the pamphlet you sent me, and I find in it that this Ba'hai movement is more or less a humanitarian movement which has no spiritual information. Generally people are attracted by humanitarian movements and Swami Vivekananda was a popular figure of this platform but this humanitarian movement of the material platform is always unsuccessful because one has to counteract the 3 modes of material platform. I do not find any hint in Ba'hai literature where one can surmount the reactions of material qualities. The idea of Ba'hai movement is more graciously presented in our Krishna Consciousness movement. The Ba'hai movement doesn't take any consideration of living entities beyond the human society. But our Krishna Consciousness movement includes everything in the creation of God. As a scholar, you can read such books but I am sure it will not help very much in the matter of advancing our Krishna Consciousness movement. Humanitarian movements is certainly very attractive for the people in general, just like if you start a movement to stop war, it will be very attractive to the people in general. But as a matter of fact, war cannot be stopped. We aren't after stopping the war, but we are after utilizing war actions for satisfying of Krishna, as Arjuna practically performed. War cannot be stopped from the material world, but it can be purified. Therefore, so called humanitarians are our target of Krishna Consciousness. Their statement about Krishna that He is an Individual chosen by God as His representative means that they have no knowledge of God. They require to learn what is God, then they will understand Krishna. Generally speaking everyone has got the conception of God, but actually they do not know what is God. That is explained in Bhagavad-gita and Srimad-Bhagavatam, therefore our knowledge of God is far better than any other one in the world. That means if the Ba'hais do not accept Krishna as the Supreme Personality of Godhead, they have never read Bhagavad-gita as it is. Their claims of reading of Gita is false. You should try to convince them of the Supremacy of Godhead Krishna. Whenever we are able to meet such opposing elements about Krishna, we should know that our Krishna Consciousness is perfected. The Ba'hai people if they are really sincere, they should try to understand Bhagavad-gita sincerely. As soon as they say they have understood Bhagavad-gita and at the same time accept Krishna as a chosen individual person, their sincerity fails. There is less rational thinking in Ba'hai philosophy as I can understand from the pamphlet. There is already contradiction that they accept Krishna as chosen person and not as the Supreme Personality of Godhead, that is contradiction of Bhagavad-gita.
