Sometimes the behavior of Kṛṣṇa's sons appears similar to the behavior of His personal servants. For example, the sons used to offer their obeisances, they were silent, submissive and gentle, and they were always ready to carry out Kṛṣṇa's orders, even at the risk of life. When present before Kṛṣṇa, they bowed down on the ground. They were very silent and steady, and they used to restrain coughing and laughing before the Lord. Also, they never discussed Kṛṣṇa's pastimes in conjugal love. In other words, devotees who are engaged in reverential devotional service should not discuss the conjugal love affairs of Kṛṣṇa. No one should claim his eternal relationship with Kṛṣṇa unless he is liberated. In the conditioned state of life, the devotees have to execute the prescribed duties as recommended in the codes of devotional service. When one is mature in devotional service and is a realized soul, he can know his own eternal relationship with Kṛṣṇa. One should not artificially try to establish some relationship. In the premature stage it is sometimes found that a lusty, conditioned person will artificially try to establish some relationship with Kṛṣṇa in conjugal love. The result of this is that one becomes prakṛta-sahajiyā, or one who takes everything very cheaply. Although such persons may be very anxious to establish a relationship with Kṛṣṇa in conjugal love, their conditioned life in the material world is still most abominable. A person who has actually established his relationship with Kṛṣṇa can no longer act on the material plane, and his personal character cannot be criticized.
When Cupid came on one occasion to visit Lord Kṛṣṇa, some devotee addressed him thus: "My dear Cupid, because you have been so fortunate as to have placed your eyesight on the lotus feet of Kṛṣṇa, the drops of perspiration on your body have become frozen, and they resemble kaṇṭaki fruits (a kind of a small fruit found in thorny bushes)." These are signs of ecstasy and veneration unto the Supreme Personality of Godhead. When the princes of the Yadu dynasty heard the vibration of Kṛṣṇa's Pāñcajanya conchshell, the hairs on their bodies immediately stood up in ecstatic jubilation. It seemed at that time that all the hairs on the bodies of the princes were dancing in ecstasy.
In addition to jubilation, there are sometimes symptoms of disappointment. Pradyumna once addressed Sāmba with these words: "My dear Sāmba, you are such a glorified personality! I have seen that once when you were playing on the ground, your body became covered with dust; yet, our father, Lord Kṛṣṇa, still took you up on His lap. But I am so unfortunate that I could never get such love from our father!" This statement is an example of disappointment in love.
To regard Kṛṣṇa as one's superior is called reverential feeling, and when, in addition to this, a devotee feels that Kṛṣṇa is his protector, his transcendental love for Kṛṣṇa is increased, and his combined feelings are called reverential devotion. When this steady reverential devotion increases further, it is called love of Godhead in reverential devotion. Attraction and affection are two prominent symptoms of this stage. In this reverential devotional attitude, Pradyumna never talked to his father in a loud voice. In fact, he never so much as unlocked the lips of his mouth, nor did he ever show his face filled with tears. He would always glance only at the lotus feet of his father.
