Srimad-Bhagavatam: Canto 9 - Chapter 1 - Verse 16

Sanskrit:

होतुस्तद्‌व्यभिचारेण कन्येला नाम साभवत् ।तां विलोक्य मनु: प्राह नातितुष्टमना गुरुम् ॥ १६ ॥

ITRANS:

hotus tad-vyabhicāreṇakanyelā nāma sābhavattāṁ vilokya manuḥ prāhanātituṣṭamanā gurum

Translation:

Manu had begun that sacrifice for the sake of getting a son, but because the priest was diverted by the request of Manu’s wife, a daughter named Ilā was born. Upon seeing the daughter, Manu was not very satisfied. Thus he spoke to his guru, Vasiṣṭha, as follows.

Purport:

Because Manu had no issue, he was pleased at the birth of the child, even though a daughter, and gave her the name Ilā. Later, however, he was not very satisfied to see the daughter instead of a son. Because he had no issue, he was certainly very glad at the birth of Ilā, but his pleasure was temporary.
