Please accept my blessings. I received your letter dated July 18, after the mail strike as well as Nandarani's letter, along with it. And I thank you very much for them. Regarding immigration: I have already received immigration in Canada, so there is no difficulty for my going to USA, but still I am trying to get immigration of religious minister into the USA, and it is progressing well. I think there will be no difficulty in coming and going to USA, either from Canada or anywhere, so don't be worried about it. Krishna will help us. Now, regarding your question: "What is the difference between Jagannatha deities and Krishna Murti and why is the latter not fed and cared for as well as the former and why are Jagannathas more tolerant?" Krishna means Himself and all His expansions, different expansions. So sometimes, Krishna appears as Vasudeva, sometimes as Sankarsana, sometimes as Jagannatha, sometimes as Lord Caitanya, sometimes as Rama, so all such different incarnations includes the Name Krishna. So Jagannatha is another feature of Krishna, and He is especially favorable to the people who are not strictly advanced to the Brahminical culture of Vedic rituals. Lord Jagannatha is situated in India, at Puri; this place is one of the towns of Orissa province. And the people of Orissa and Bengal, they are sometimes fish-eaters, why sometimes—about 90% population they are fish-eaters. But Jagannatha Swami in Puri, He accepts service from these people although they are sometimes fish-eaters. So in the Kali yuga, the people are supposed to be not so clean, and therefore, service to Jagannatha Swami is preferred. So far service to Laksmi-Narayana, and Radha Krishna, it requires highly elevated position, transcendental to Brahmins. But still, either we serve Jagannatha or Radha Krishna, the effect is the same. But to facilitate the worship of the Lord in the Form of Jagannatha is more congenial than others. But when anything is offered to Jagannatha, it does not mean that it is not taken by Krishna. So in the temple, although we offer to Jagannatha, it is also accepted by Krishna. Be rest assured of this fact.
Regarding your question: "What is the correct sexual etiquette for a strict Grhastha; and what is spiritual family planning?" Unless one wants to beget a child, there should not be any sex life. The best thing is to forget sex, but it is not possible immediately or all of a sudden, especially in the Western countries where sex life is so liberal. So under the circumstances, one should try to have sex life only for children, not for any other purpose. Spiritual family planning is that one should be determined to train up children in Krishna Consciousness. According to Bhagavata, the spiritual family planning is that one should not become a father or one should not become a mother, unless he is able to maintain their children to the extent of liberation. It is the duty of the parents to see that the children are growing luxuriantly not only materially, but spiritually also. So spiritual training should be given from the very beginning. Kaumaram acaret prajna—In the Srimad-Bhagavatam, Prahlada Maharaja has instructed that spiritual consciousness or Krishna Consciousness should be taught to the children from the very beginning as they are given education from early childhood.
