My Dear Tosana Krishna,
Please accept my blessings. I was in due receipt of your letter dated Sept. 30, 1968, but for want of time I could not reply earlier. I am pleased to learn that you are finding association with Subala very nice, because he is a sincere devotee of Krishna. Certainly you will find a good association.
Regarding your question about this planet and Krishna's coming here, you may note that Krishna comes within this universe once in one day of Brahma. Duration of Brahma's day is very very long, it is stated in the Bhagavad-gita—432 crores of years forms the duration of 12 hours of Brahma's day. And similarly, there are 12 hours of night, so after 864 crores of years, Krishna comes in this universe, and whenever He comes, He of course, appears on this planet, that is the fortune of the people of this planet. We should know very clearly that Krishna is the Supreme Personality of Godhead. He is neither Indian nor American, as much as the sun is neither Indian nor American. The original name of this planet is called Bharatavarsa, and before that it was known as Ilavrtavarsa. Now since the day of Emperor Bharata, this planet is know as Bharatavarsa, but in course of time, the human race divided, therefore we find so many other names. But the original name of this planet is Bharatavarsa, and in the Vedic literature, it is stated that anyone who takes birth on this planet, they are very fortunate. Because it is the special planet where Krishna descends when He comes.
Regarding your proposal to become a doctor, because your mother wants to prosecute your education, I think if you can learn Krishna Consciousness perfectly, by reading our different literatures, and books, you will be a better doctor than the ordinary physician. The ordinary physician may cure the disease of the body, but if you become advanced in Krishna Consciousness, you will be able to cure the disease of the soul for many many persons. And that is more important than a doctor or medical practitioner for curing the disease of this body. However we may be expert for keeping this body fit, it is sure and certain that this will end. But if you can protect the soul from being fallen a victim of this material existence that is a greater service. In some of the Vedic literatures, it is said that Atmanan Sarvato Rakshet, that means one should give first protection to the soul. Then he should take care of his particular type of faith, then he should take care of the material things, namely this body, and anything in relation with this body, or wealth. Please try to read all our books very carefully, and whenever there is any doubt, you ask me, and be expert preacher. That will make you a great doctor for protecting the human society from being fallen a victim to maya. I hope this will meet you in good health,
Yours ever well-wisher,
A.C. Bhaktivedanta Swami
