Jayapataka Swami: If you carry out the order of the spiritual master, it is considered that your motives are good. And even if you have some other desires those in due course will be mitigated and you will be able to engage in devotional service purely. We heard in a letter from Srila Prabhupada to Janaki mataji where he said that all the devotees who come to him are basically pure devotees. So even if some people had some external desires or motives that in due course those will be satisfied by Krsna and their pure devotional service will be manifest, because they are following the process that Srila Prabhupada gave. Haribol!
