The sadhu... I have explained several times. Sadhu means devotee. Sadhu does not mean the worldly honesty or dishonesty, morality or immorality. It has nothing to do with material activities. It is simply spiritual, sadhu. But sometimes we derive, "sadhu," a person's material goodness, morality. but actually "sadhu" means in the transcendental platform. Those who are engaged in devotional service. Sa gunan samatityaitan [Bg. 14.26]. Sadhu is transcendental to the material qualities. So paritranaya sadhunam. The paritranaya means to deliver.
Now if a sadhu is already delivered, he is on the transcendental platform, then where is the necessity of delivering him? This is the question. Therefore this word is used, vidambanam. It is bewildering. It is contradictory. It appears to be contradictory. If a sadhu is already delivered... Transcendental position means he's no longer under the control of the three material modes of nature, goodness, passion and ignorance. Because it is clearly stated in the Bhagavad-gita: sa gunan samatityaitan [Bg. 14.26]. He transcends the material qualities. A sadhu, devotee, Then where is the question of deliverance? The deliverance... He does not require deliverance, a sadhu, but because he is very much anxious to see the Supreme Lord eye to eye, that is his inner desire, therefore Krsna comes. Not for deliverance. He's already delivered. He's already delivered from the material clutches. But to satisfy him, Krsna is always...
Just like a devotee wants to satisfy the Lord in all respects, similarly more than the devotee, the Lord wants to satisfy the devotee. This is the exchange of loving affairs. Just like in your, in our ordinary dealings also, if you love somebody, you want to satisfy him or her. Similarly, she or he also wants to reciprocate. So if that reciprocation of loving affairs is there in this material world, how much it is greatly elevated in the spiritual world? So there is a verse that: "Sadhu is My heart, and I am also the sadhu's heart." The sadhu is always thinking of Krsna and Krsna is always thinking of His devotee, sadhu.
So the appearance and disappearance of Lord within this material world, that is called cikirsitam.
