To facilitate these activities of the human being, there is spiritual master. Spiritual master is the representative of God. Therefore Vedic literature says, tad-vijṣānārtham. In order to understand whether God is being satisfied or not, tad-vijṣānārthaṁ sa gurum evābhigacchet (Muṇḍaka Upaniṣad 1.2.12), one must approach a spiritual master in order to know. Because my life is meant for satisfying God, but understanding that God is not present in my front, I cannot see Him face to face, how can I know that He is satisfied or not?
But there are books, scriptures, literatures. Apart from that, the Vedic injunction is that tad-vijṣānārtham. In order to understand whether your action or activities has pleased the Supreme Personality of Godhead, you have to take information from the guru, or the spiritual master. Tad-vijṣānārthaṁ sa gurum evābhigacchet. Abhigacchet means "must." And in the Viśvanātha Cakravartī's prayer for the spiritual master, this is also said: yasya prasādād bhagavat-prasāda.
The last version of his prayer is yasya, "whose"; prasādāt, "satisfaction"; bhagavat-prasāda, "the Supreme Lord is satisfied." This is the test.
