Meaning and elaboration
Meaning: The Goddess within whose womb the whole universe abides.
Elaboration
The name Devy'udāra literally suggests the Goddess whose udāra is the abode of the universe. Here udāra can mean womb, belly, or inner chamber. The name therefore presents Kali as the living interior of existence itself, the one in whom the cosmos is held, sustained, and finally gathered back.
The Cosmic Womb and Stomach Udāra carries a deliberate double meaning in this name. It is the womb from which creation comes forth and is nourished, and it is also the stomach into which all things are ultimately drawn back. In that sense, Kali is both mother and devourer. The worlds rest in her as a child rests in the womb, and at the end of time they return into her without remainder.
All-Encompassing Nature This points to her all-pervading nature, her Sarvavyāpini aspect. Galaxies, stars, planets, beings, and subtle worlds all abide within her. She is not merely a power acting somewhere inside the universe. She is the very ground that contains it, pervades it, and still remains beyond it. Like space, she holds all things without ever being confined by any of them.
Cycle of Creation and Dissolution As the cosmic stomach, she reabsorbs whatever she has brought forth. Whatever is created is eventually gathered back, dissolved, and assimilated into her own being. This reflects the sacred rhythm of Kāla: creation (Sṛṣṭi), sustenance (Sthiti), and dissolution (Saṃhāra). From her cosmic womb all things emerge; into her they return. This is not blind destruction, but holy reabsorption, a return to the source.
Dependence of All Existence The name also reveals how completely all manifest existence depends upon her. Just as a child lives by the mother's womb, all beings and all phenomena are sustained within Devy'udāra. To meditate on her in this form is to recognize her as the source, the support, and the final resting place of one's own life and of the whole cosmos.
