Prabhupāda: Hmm. Dharmārtha-kāma, kāma-mokṣaḥ samaya-pratīkṣāḥ muktiḥ mukulitañjali sevate asmān (Kṛṣṇa-karṇāmṛta 107). For a devotee, mukti is not a thing aspirable, because, as it is stated by Bilvamaṅgala Ṭhākura, mukti is trying to serve the devotee with folded hands. Because a devotee is already liberated. Sa guṇān samatītyaitān brahma-bhūyāya kalpate (BG 14.26). A pure devotee, who is constantly engaged in devotional service, māyā cannot touch him. He's already liberated. So what he has got to ask from the liberty? He hasn't got to ask. Anywhere a devotee lives, he's liberated.
That is the statement of Śrīla Rūpa Gosvāmī, īhā yasya harer dāsye karmaṇā-manasā vācā: "Anyone who is simply engaged in the devotional service of the Lord by his activities, karmaṇā, by his mind and by his words, such person is always liberated in any condition of life." Īhā yasya harer dāsye. Simply we have to engage ourself in the devotional service of the Lord, then māyām etāṁ taranti te (BG 7.14). One who has surpassed the boundaries of māyā, he's liberated. He's liberated. He's already liberated. Why he should aspire after liberation? He's already liberated.
Go on.
Pradyumna: "Any kind of happiness derived from religiousness, economic development, liberation or sense gratification cannot even dare to enter into the heart of a pure devotee. It is stated that as the personal attendants and maidservants of a queen follow the queen with all respect and obeisances, similarly, the joys of religiousness, economic development, sense gratification and liberation follow the devotional service of the Lord. In other words, a pure devotee does not lack any kind of happiness derived from any source. He does not want anything but service to Kṛṣṇa. But even if he should have another desire, the Lord fulfills this without the devotee's asking."
Prabhupāda: Yes. Generally, a devotee is anyābhilāṣitā-śūnyaṁ jñāna-karmādy-anāvṛtam (Brs. 1.1.11). He's simply engaged to serve the Lord as He desires, just like Arjuna did. Other things follow. Just like a child who takes shelter of the father without any demand, the father sees to his necessities of life. Yoga-kṣemaṁ vahāmy aham (BG 9.22). Kṛṣṇa, one who is fully surrendered unto Kṛṣṇa, and he's engaged in His devotional service, He would see what is the necessity of his life, what does he require. Yoga-kṣemaṁ vahāmy aham. This is the process.
Go on.
Pradyumna: " 'Rareness of Pure Devotional Service.' In the preliminary phase of spiritual life there are different kinds of austerities, penances and similar processes for attaining self-realization. However, even if an executor of these processes is without any material desire, he still cannot achieve devotional service. And aspiring by oneself alone to achieve devotional service is also not very hopeful, because Kṛṣṇa does not agree to award devotional service to merely anyone. Kṛṣṇa can easily offer a person material happiness or even liberation, but He does not agree very easily to award a person engagement in His devotional service."
Prabhupāda: This is very confidential. To attain Kṛṣṇa's service, that is not so easy. You can get liberation—if you want from Kṛṣṇa, Kṛṣṇa can give very easily—or any material opulence. But to give engagement in devotional service, that requires very sincerity. As it is stated by Rūpa Gosvāmī, anyābhilāṣitā-śūnyaṁ (Brs. 1.1.11). People generally go to temple and churches for mitigating some material wants. Ārto arthārthī. Jijñāsī jñānī ārto arthārthī. Generally, people go to Kṛṣṇa to mitigate some material distresses, ārto, or one who is in need of money.
Just like Dhruva Mahārāja. He went to Kṛṣṇa . . . he went to worship Kṛṣṇa under the instruction of his mother in the forest with a desire to achieve the kingdom of his father or better, better kingdom than his father. That was his aspiration. But later on, when he actually met the Supreme Personality of Godhead, he said: "My dear Lord, I have no other aspiration. I am completely satisfied." Svāmin kṛtārtho 'smi varaṁ na yāce (CC Madhya 22.42).
So this is the advantage of worshiping Kṛṣṇa. Even one has got some material desires, that material desires will be fulfilled. At the same time, he shall become a pure devotee, just like Dhruva Mahārāja became. He went to worship the Supreme Personality of Godhead, fulfillment, for fulfilling his material desires, but because he engaged himself in severe austerity and penances for having darśana, or seeing the Supreme Personality of Godhead, when he saw Him actually he forgot all his material desires. That is the advantage.
