Srila Prabhupada gave us a mission to fulfill in this world. That mission is simply to execute his order. Therefore, it is a far more important meditation for his disciples to think of his order than to imagine their lives with him in the spiritual world. When we are ready, the spiritual master will reveal more to us about our mutual identities in the spiritual world. We qualify ourselves for that revelation by following his orders in the here and now. Srila Prabhupada never spoke about his relationship with Srila Bhaktisiddhanta in the spiritual world, nor did he speak to his disciples about our relationship with him in Goloka. We should understand that Srila Prabhupada did not speak about such things for a reason; Prabhupada wanted us to live with him by mediatation on the instructions he gave us in this world.
