Lecture on Srimad Bhagavatam, Canto 10, Chapter 1, Text 23 titled “Entrances and Exits”.
Srimad Bhagavatam 10.1.23
The Supreme Personality of Godhead, Sri Krishna, who has full potency, will personally appear as the son of Vasudeva. Therefore all the wives of the demigods should also appear in order to satisfy Him.
In Bhagavad-gita (4.9) the Lord says, tyaktva deham punar janma naiti mam eti: [Bg. 4.9] after giving up the material body, the devotee of the Lord returns home, back to Godhead. This means that the devotee is first transferred to the particular universe where the Lord is at that time staying to exhibit His pastimes. There are innumerable universes, and the Lord is appearing in one of these universes at every moment. Therefore His pastimes are called nitya–lila, eternal pastimes. The Lord’s appearance as a child in the house of Devaki takes place continuously in one universe after another. Therefore, the devotee is first transferred to that particular universe where the pastimes of the Lord are current. As stated in Bhagavad-gita, even if a devotee does not complete the course of devotional service, he enjoys the happiness of the heavenly planets, where the most pious people dwell, and then takes birth in the house of a suci or sriman, a pious brahmana or a wealthy vaisya (sucinam srimatam gehe yoga-bhrashto ‘bhijayate). Thus a pure devotee, even if unable to execute devotional service completely, is transferred to the upper planetary system, where pious people reside. From there, if his devotional service is complete, such a devotee is transferred to the place where the Lord’s pastimes are going on. Herein it is said, sambhavantu sura–striyah. Sura–stri, the women of the heavenly planets, were thus ordered to appear in the Yadu dynasty in Vrindavana to enrich the pastimes of Lord Krishna. These sura–stri, when further trained to live with Krishna, would be transferred to the original Goloka Vrindavana. During Lord Krishna‘s pastimes within this world, the sura–stri were to appear in different ways in different families to give pleasure to the Lord, just so that they would be fully trained before going to the eternal Goloka Vrindavana. With the association of Lord Krishna, either at Dvaraka–puri, Mathura–puri or Vrindavana, they would certainly return home, back to Godhead. Among the sura–stri, the women of the heavenly planets, there are many devotees, such as the mother of the Upendra incarnation of Krishna. It was such devoted women who were called for in this connection.
