One meets Srila Prabhupada by the will of providence. And therefore by meeting him through his instructions we can actually connect ourselves to the sampradaya. We do not say that it is siksa alone which qualifies one to go back home. One must also take diksa in an authorized sampradaya. But it is described that diksa is an ongoing process. Diksa doesn't take place in one day at one fire sacrifice. Diksa means divya jnana, which means giving transcendental knowledge. When one takes diksa in our sampradaya, the transcendental knowledge must continue to come through in order to complete that process of diksa.
