10.184.1

विष्णु॒र्योनिं॑ कल्पयतु॒ त्वष्टा॑ रू॒पाणि॑ पिंशतु ।
आ सि॑ञ्चतु प्र॒जाप॑तिर्धा॒ता गर्भं॑ दधातु ते ॥

May Viṣṇu prepare the womb, and Tvaṣṭā shape the forms. May Prajāpati pour here, and Dhātā establish your embryo.

गर्भं॑ धेहि सिनीवालि॒ गर्भं॑ धेहि सरस्वति ।
गर्भं॑ ते अ॒श्विनौ॑ दे॒वावा ध॑त्तां॒ पुष्क॑रस्रजा ॥

Hold the embryo, O Sinīvālī; hold the embryo, O Sarasvatī. May the two Aśvins, wearing lotus garlands, place your embryo here.

हि॒र॒ण्ययी॑ अ॒रणी॒ यं नि॒र्मन्थ॑तो अ॒श्विना॑ ।
तं ते॒ गर्भं॑ हवामहे दश॒मे मा॒सि सूत॑वे ॥

The golden fire-sticks from which the two Aśvins churn out fire — that embryo we call for you, for birth in the tenth month.
