In the Tenth Canto, 68th Chapter, 30th verse of Śrīmad-Bhāgavatam, there is an account of Rukmiṇīdevī's writing a letter to Kṛṣṇa requesting Him to kidnap her before her marriage to another person. At that time the specific attachment of Rukmiṇī for Kṛṣṇa was expressed by Rukmiṇī as follows: "My dear Lord Kṛṣṇa, Your transcendental glories are chanted by great sages who are free from material contamination, and in exchange for such glorification You are so kind that You freely distribute Yourself to such devotees. As one can elevate oneself simply by Your grace, so also by Your direction alone one may be lost to all benedictions under the influence of eternal time. Therefore I have selected Your lordship as my husband, brushing aside personalities like Brahmā and Indra—not to mention others." Rukmiṇī enhanced her love for Kṛṣṇa simply by thinking of Him. This is an instance of thoughtfulness in ecstatic love.
When a person is fully satisfied due to attaining knowledge, transcending all distress, or achieving his desired goal of life in transcendental devotional service to God—at that time his state of endurance or steady mind is called dhṛti. At this stage one is not perturbed by any amount of loss, nor does anything appear to be unachieved by him.
According to the opinion of Bhartṛhari, the learned scholar, when a person is elevated to this state of endurance, he thinks as follows: "I do not wish to be a highly posted government servant. I shall be satisfied even if I have to eat food collected by begging. I shall prefer to remain naked, without proper dress of garments. I shall prefer to lie down on the ground without any matress. And despite all these disadvantages, I shall refuse to serve anyone, not even the government." In other words, when one is in ecstatic love with the Personality of Godhead, he can endure any kind of disadvantages calculated under the material concept of life.
Nanda Mahārāj, the father of Kṛṣṇa, used to think: "In my pasturing ground the goddess of fortune is personally present, and I possess more than ten hundred, thousand cows which loiter here and there. And above all, I have a son like Kṛṣṇa, who is such a powerful, wonderful worker. Therefore, even though I am a householder, I am feeling so satisfied!" This is an instance of mental endurance resulting from the absence of all distress.
