सोष्यन्तीमद्भिरभ्युक्षति यथा वायुः पुष्करिणीं समिङ्गयति सर्वतः ।एवा ते गर्भ एजतु सहावैतु जरायुणा ।इन्द्रस्यायं व्रजः कृतः सार्गलः सपरिश्रयः ।तमिन्द्र निर्जहि गर्भेण सावरां सहेति ॥बृह. ६,४.२३ ॥

When she is about to bring forth, he sprinkles her with water, saying: "As the wind stirs a lotus pool on every side, so let thy child stir, and come down together with the afterbirth. This fold of Indra's has been made, with a bolt and a barrier about it. Drive it forth, O Indra — the child and the afterbirth together."
