In the Vaiśākha-māhātmya section of the Padma Purāṇa a devotee states that though in some of the eighteen Purāṇas the process of glorifying Lord Viṣṇu is not mentioned and the glorifying of some demigod is offered, such glorification must be continued for millions of years. For when one studies the Purāṇas very scrutinizingly, he can see that ultimately Lord Viṣṇu is the Supreme Personality of Godhead. This is an instance of ecstatic love developed out of thoughtfulness.
In the Tenth Canto, Sixtieth Chapter, verse 39, 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.
