Saṁsiddhi means perfection. So perfection, if we want perfection of our activities, then we shall try to satisfy by our activities the Supreme Personality of Godhead. You may say that "I do not see the Supreme Personality of Godhead face to face. How I shall be able to know that I am satisfying or dissatisfying Him?" That you can know through your spiritual master. It is not very difficult. If your spiritual master is satisfied, then you should know that Kṛṣṇa is satisfied. Yasya prasādād bhagavat-prasādaḥ **. There is no difficulty. Yasyāprasādān na gatiḥ kuto 'pi. You cannot satisfy Kṛṣṇa by dissatisfying your spiritual master. That is not possible. That is not possible. You must satisfy. Yasya prasādād bhagavat-prasādaḥ **. You do not take the excuse that "I do not know God, I do not meet Him. How I shall know that I have satisfied Him or dissatisfied Him?" No, śāstra says, "Yes..." It doesn't matter. Therefore it is called paramparā. Paramparā. As you receive the knowledge from Kṛṣṇa, from Arjuna, and from Nārada, from Brahmā, like that, come down to your spiritual master, similarly, as you receive the knowledge step by step, one after another, similarly, you satisfy also the Supreme Personality of Godhead from this step, this step, this step, this step. This is the process. Just like you come down step by step by step by step, similarly you go up step by step by step by step.
So this is the process, bhagavat-toṣaṇam or hari-toṣaṇam. Also this way. And to receive the knowledge from Bhagavān, that is also paramparā system. The paramparā system must be maintained, and if it is done nicely, then as it is stated here, yad atra kriyate, whatever you do, that is for your perfection. If you keep this paramparā system and if you try to satisfy the Supreme Personality of Godhead, then whatever you do, that is perfection. It doesn't matter. The test is whether Kṛṣṇa is satisfied, whether your spiritual master is satisfied. Then you are perfect.
