"Regarding your question, the Supreme Personality of Godhead is recognized through the sastras not otherwise. For instance, in the Srimad-Bhagavatam, first canto, third chapter, all the major incarnations of Godhead are listed. Many times the scheduled time of appearance and family, etc. are also mentioned. The incarnation of Godhead must be indicated in the scriptures, otherwise we cannot accept him as being incarnation. Today, there are so many bogus incarnations, but we do not accept them. The Supreme Lord can appear in this world at any time, but he does so according to the regular scheduled appearances mentioned in the sastras. According to the sastras, the last most recent incarnation was Sri Caitanya Mahaprabhu who appeared in West Bengal about 500 years ago. We are following in direct line of disciplic teaching from Him.
Another point is that the words of the Lord have been recorded in the Bhagavad-gita, so if someone comes claiming to be incarnation, but also contradicts the Bhagavad-gita, then we can be sure he is phony. Please try to read and understand my books very carefully. All these things are explained."

"I wish to thank you very much for your reading our books so carefully and scrutinizingly. Any man who reads these literatures will find a storehouse of transcendental information. I hope you will continue to study so nicely on a daily basis as you have described in your letter.
Regarding your question, you may refer to Adi-lila, Chapter 6, Text 79 along with the purport, (Caitanya-caritamrta). The answer is there. The basic understanding is that Sada-Siva is an expansion of Maha-Visnu and that same Sada-Siva incarnates as Advaitacarya. Therefore, since Advaitacarya is an incarnation of Sada-Siva who is non-different from Maha-Visnu, we can say that Advaitacarya is an incarnation of Maha-Visnu. It can be said both ways, that He is an incarnation of Sada-Siva or Maha-Visnu."

"Regarding your question at the end, yes, the soul is eternal and it is transmigrating from one body to another. Therefore the body is undergoing evolution, not the soul. Just like if I come to the USA from India, I have to change my residence. I personally do not have to change, but my residence changes. So, the soul travels from one body to another and always remains the same."
(Srila Prabhupada Letter, June 8, 1975)
"Regarding your question about the jiva soul in the heart and the jiva soul within the cells, they are separate. Both are jiva atmas, but a particular jiva belongs to a particular body. There is the jiva in this body, but there are also jivas within the cells. Just like I am living within this apartment, but does it mean that no other living entity can live here. There are so many ants, flies, bugs, they are also living within the apartment. Even in my stool there are thousands of living entities.
Your second question is not very clear what you want to ask, but the fact is that each and every living entity is covered by two kinds of bodies, one subtle and one gross. So the subtle body causes the living entity to take another gross body. We have got experience that in dreaming the gross body is inactive while the subtle body is continuing activities; and again in deep sleep the subtle body is continuing activities. The living entity after being carried by the subtle body to another gross body, it sometimes remains in deep sleep in the womb of the mother. Then gradually the subtle body begins to act within another gross body. When this gross body is fully developed befitting to come out of the mother's body, that is called another birth. Again he changes to another gross body imperceptibly. Just like in the film thousands of pictures are moved imperceptibly. It looks that the body in the picture is moving, but the audience cannot understand that there are so many pictures in the spool. They think that the picture is moving. Similarly every second every moment we are changing the body.
Those who are not sober cannot understand how the spirit soul is changing from one body to another. Krsna therefore says that this change of body can be appreciated only by the dhiras. dhiras tatra na muhyati (BG 2.13). While those who are not dhiras cannot understand how the soul is changing from one body to another. There are two kind of men, dhira and adhira. The modern education is producing only the adhira class who are neither sober or educated. Therefore the majority of the population cannot understand how the soul is transmigrating from one body to another. They are only interested in wine and woman under the impression of the bodily concept of life. Therefore out of so many scientists in this country only you and the few others are understanding the importance of this subject matter. manusyanam sahasresu (BG 7.3). So please work very hard, following our rules and regulations and you will always remain in the fire of Krsna consciousness."

"Regarding your question, so long they are not getting the human form by natural elevation, they are under the laws of nature. 'prakrteh kriyamanani, gunaih karmani sarvasah (BG 3.27),' Material nature is helping to bring him to the human body, or human species. When a human being is civilized he can take knowledge from Vedic literature. So in Kali Yuga the Srimad-Bhagavatam is the essence of Vedic literatures: nigama kalpa taror galitam phalam (SB 1.1.3).
So by study of Srimad-Bhagavatam under the bona fide spiritual master, one becomes aware of the full value of life, and then he revives his original Krishna consciousness. That is the perfection of life. The individual soul is already under specific material nature, and the process is going on in lower grades of life, but in the human form of life by advancement of education, one can become above the modes of material nature. That chance is given to him. This is stated in the Bhagavad-gita: 'yanti deva vrata devan (BG 9.25).' So if he likes he can go back to Godhead, 'yanti mad yajino 'pi mam,' and stop this transmigration process. Then he comes again perfect in Krishna consciousness. We are trying to bring the human society to this stage of life.
In human life even in the lower stage of modes of nature, he can come to the higher stage. That is our movement. In the animal form there is no chance, only in the human form. Unfortunately the modern mode of education is to kill the chance. In animal stage of life it is very dangerous."
(Srila Prabhupada Letter, August 31, 1975)
"Regarding your question about the difference between the mind and the soul, in the Bhagavad-gita it is directly said that the mind is inferior energy in a subtle form, and soul, jiva, is superior energy. So they are completely distinct. Mind is not spiritual, but mind is a subtle material form. When the soul becomes captivated for enjoying the material world instead of rendering service to Krishna, that is the beginning of his falldown. When the living being thinks himself to be the enjoyer, that is called false ego. His constitutional position is to serve Krishna. So this false egotism degrades him to pollute the intelligence and the mind.
So mind and intelligence are already there in the soul, but in the conditional stage the same mind and intelligence become polluted as false egotism or enjoyer. The bhakti process is to purify everything. The mind is not the soul but is a venue for expressing the soul's desire. So if the mind is purified, then things go on nicely in its original position. If he does not go on rightly he falls down in conditional life. The whole yogic system is to convert the mind from matter to spirit. You can utilize the mind in both ways. When the mind is spiritually trained up it is the best friend of the soul, and when the mind is materially polluted, it is the worst enemy. The Bhagavad-gita states:
bandhur atmatmanas tasya yenatmaivatmana jitah
anatmanas tu saturve vartetatmaiva satruvat
For those who are grossly materialistic persons, for them the yogic system is recommended, otherwise if the mind is directly engaged engaged at the lotus feet of Krishna, the senses automatically become engaged in Krishna's service; and that is the liberated stage. Chanting of the Hare Krishna mantra is the direct process for curing the mind of all materialistic contamination. Take to this process and be happy."
