Regarding the grhasthas houses, we have given these houses with the purpose that they should execute devotional service exactly like the Brahmacaris and sannyasis. Otherwise, why purchase houses near the temple? The whole idea is to live near the temple and take advantage of the temple program, which means morning arati, classes, sankirtana and all services connected with the temple. They are also members of the temple.
Locana das may deposit his contributions with the Mayapur Vrindaban fund which will also go for the Krsna Balarama temple as is his desire. I am still not aware how fast the remittance is going from the Union Bank to the Punjab National Bank in Vrindaban. For example I have not received a report on when the interest for April, due payable April 10, actually reached Vrindaban. I have written the Punjab National Bank about this and am awaiting their report.
You have asked about Gaura Nitai deity worship by the householders in Los Angeles. That is for those who live far away from the temple and cannot attend. Otherwise, such worship is redundant; there is already deity worship going on in the temple and they should attend the aratis, not install their own deities. The impression of Lord Caitanya's feet which you have there may be kept in a picture, not that it is worshiped as a deity. Keep it as a picture.
Regarding your invitation that I attend the Rathayatra festival in San Francisco, on July 7th, it is possible that I may attend depending on when I finish my European tour. I am due to arrive in Rome on May 23, then after a week Geneva, the Paris and possible Stockholm, Germany and England. If there is time I can fly directly from Europe to Los Angeles and go to the festival, then as you suggest, go to Australia Rathayatra via Hawaii. This is known as jet-age parivrajakacarya. For the present I will be staying in Bombay for about two weeks, then to Delhi and Vrindaban before leaving for Rome.
