Brahmacharies and Brahmacharinis can live in the temple provided there is separate arrangement. The restriction is there because if they live together there might be sex impulses agitated. The whole principle is especially for the Brahmacharies to avoid causes which may give impetus to the sex desire. But in your country it is very difficult to make aloof the boys and girls because they are accustomed to mix together. So it is not possible for me to introduce this new system very strictly, because they are trained differently. Someway or other, if you are intelligent boy, you should make arrangement for the boys and girls to live separately; Brahmacharies at one place all together, and the Brahmacharinis all together at another place. We should always remember that sex life in spiritual advancement is great impediment. So keeping this point of view in front, we should intelligently manage things with great care. So that our aim of life may not be missed.
Maharaj Dasarath, although he was a great devotee of the Lord, but because he was a Kshatriya king, keeping one's promise is inevitable for him. He preferred to banish Ramachandra on the request of his wife on the principle of keeping his promise. In higher states of spiritual life, one can break even promises also, but they are devotees of comparative merit. In the case of Vasudev, we find that he was spiritually more advanced than Maharaj Dasarath. Vasudev was also in agreement with Kamsa that he would deliver all his sons to his hand, as soon as the child is born. But in the case of Krishna he broke his promise. The point is that Krishna appeared as the full fledged Supreme Personality of Godhead. But Ramachandra appeared as an ideal king.
