Yajña means Viṣṇu. Whatever you do, if it is for Kṛṣṇa, then you are liberated. Otherwise, karma-bandha; you are bound up by the laws of nature, karma-bandha. So karma-bandha yān mūlaḥ. If we act for our sense gratification, then this kāma-krodha is bondage. And if we don't accept this karma-bandha, then you are liberated. Very easy thing. So we have to purify our desires. Sarvopādhi vinirmuktaṁ tat-paratvena nirmalam (CC Madhya 19.170). When we give up this conception of life that "I am Indian," "I am Christian," "I am Hindu," "I am this and that . . ." These are upādhis. So while serving Kṛṣṇa, don't come back to the upādhi platform, that "We are Indians and they are Europeans, so they are taking more advantage and we are not given advantage," or visa versa. This means coming back to the upādhi. That is not the stage of devotion. We have to become free from the upādhi. "I am neither Indian nor American. I am eternally Kṛṣṇa's servant, that's all. Whatever Kṛṣṇa orders, in whichever position He keeps me, I am His eternal servant." This is upādhi-mukta-nirmalam, pure stage.
Now, when we are in the pure stage, the same kāma, the same manyu, the same mada lobhaḥ śoka, śoka, lamentation . . . Just like the gopīs, they were lamenting, "Kṛṣṇa is going to Mathurā," and He has gone there, the lamentation is there. But this lamentation and our lamentation not the same. Therefore in the beginning, the neophyte devotees, they should not try to understand the dealings of the gopīs with Kṛṣṇa. They should not try to understand. Unless one is free from the material concept, sarvopādhi vinirmuktaṁ tat-paratvena nirmalam (CC Madhya 19.170) . . . That means we have to execute devotional service in the regulative principles. "I cannot follow the regulative principle and I am trying to understand Rādhā-Kṛṣṇa prema," this is rascaldom. This is rascaldom. Only rascals will do that. He does not see his position, that "What is my position? I am still full of lusty desires. My mind is still disturbed by seeing a nice woman, a nice man, and I am discussing Rādhā-Kṛṣṇa?" This is nonsense. Narottama dāsa Ṭhākura said, rūpa-raghunātha pade haibe ākuti kabe hāma bujhabo se yugala-pīriti. Unless you are expert in devotional service, by practical application of the instruction of Bhakti-rasāmṛta-sindhu—rūpa-raghunātha pade haibe ākuti—then if we are qualified, then someday we may be able to understand what is yugala-pīriti, love between Kṛṣṇa and Rādhārāṇī. Not so suddenly. That is sahajiyā. Not so suddenly. We should not try to do that. First of all I must see how much I have become sarvopādhi vinirmuktam, how much I am free from the designational position. Then we shall be able.
