43   In the autumn season all the birds, beasts, and men become sexually disposed, and the bull, the stag, the male bird, the man, and the other male creatures forcibly impregnate the fair sex. A similar impregnation takes place as a result of devotional service to the Lord.
Devotional service to the Lord never goes in vain. Just at the right moment, the result of one's particular devotional service will come, even if one has no desire for it. The pure devotees do not wish any return from the Lord in exchange for their service; they do not make business exchanges with the Lord. But the Lord, out of His own accord, fulfills all the desires of the devotees.
It may appear that a devotee of the Lord is becoming poorer and poorer in terms of material prosperity, but factually he is not. The typical example is the Pāṇḍavas. The five brothers, headed by King Yudhiṣṭhira, underwent all sorts of difficulties because of the conspiracy of their cousins, headed by Duryodhana, but in the long run King Yudhiṣṭhira was enthroned by Lord Śrī Kṛṣṇa, and his enemies were vanquished. King Yudhiṣṭhira was never disturbed by all the calamities that overcame them even though Lord Kṛṣṇa was ever their companion. The Pāṇḍavas never prayed to the Lord for anything but His devotional service, and in due time everything came out in favor of the devotees.
