This mentality of the direct servitor of Kṛṣṇa is called dhūrya. According to expert analytical studies of the direct associates of the Lord, Śrīla Rūpa Gosvāmī has divided these into three classes—namely dhūrya, dhīra and vīra. Raktaka is classified among the dhūrya, or those who are always attached to serving the most beloved gopīs.
One dhīra associate of Kṛṣṇa is the son of Satyabhāmā's nurse. Satyabhāmā is one of the queens of Lord Kṛṣṇa in Dvārakā, and when she was married to Kṛṣṇa, the son of her nurse was allowed to go with her because they had lived together from childhood as brother and sister. So this gentleman, the son of Satyabhāmā's nurse, used to live with Kṛṣṇa as His brother-in-law, and sometimes as brother-in-law he used to play jokes with Kṛṣṇa. He once addressed Kṛṣṇa in this way: "My dear Kṛṣṇa, I never tried to gain the favor of the goddess of fortune, who is married to You, but still I am so fortunate that I am considered one of the members of Your house, the brother of Satyabhāmā."
A vīra associate once expressed his pride, declaring, "Lord Baladeva may be a great enemy of Pralambāsura, but I have nothing to worry about from Him. And as far as Pradyumna is concerned, I have nothing to take from him, because he is simply a boy. Therefore I do not expect anything from anyone else. I simply expect the favorable glance of Kṛṣṇa upon me, and so I am not even afraid of Satyabhāmā, who is so dear to Kṛṣṇa."
In the Fourth Canto of Śrīmad-Bhāgavatam, Twentieth Chapter, verse 28, King Pṛthu addresses the Lord, saying, "My dear Lord, it may happen that the goddess of fortune becomes dissatisfied with my work, or I may even have some misunderstanding with her, but I will not mind this, because I have full confidence in You. You are always causelessly merciful to Your servants, and You consider even their menial service to be very much advanced. So I have confidence that You will accept my humble service, although it is not worthy of being recognized. My dear Lord, You are self-sufficient. You can do anything You like without the help of anyone else. So even if the goddess of fortune is not satisfied with me, I know that You will always accept my service anyway."
