BṚHADĀRAṆYAKA UPANISHAD · 6.4.17

अथ य इच्छेद् -- दुहिता मे पण्डिता जायेत सर्वम् आयुर् इयाद् इति तिलौदनं पाचयित्वा सर्पिष्मन्तम् अश्नीयाताम् ।
ईश्वरौ जनयितवै ॥

atha ya icched -- duhitā me paṇḍitā jāyeta sarvam āyur iyād iti tilaudanaṃ pācayitvā sarpiṣmantam aśnīyātām ।
īśvarau janayitavai ॥

Now, in case one wishes, 'That a learned (pandita) daughter be born to me! that she attain the full length of life!'--they two should have rice boiled with sesame and should eat it prepared with ghee. They two are likely to beget [her].
