अग्नीषोमोत्पत्तिः
Agni–Soma Origin and the Brahmāgnīṣomīya Doctrine
यस्मिन् पारिप्लवा दिव्या वहन्त्यापो विहायसा । पुण्यं चाकाशगज़जायास्तोयं विष्टभ्य तिष्ठति
yasmin pāriplavā divyā vahanty āpo vihāyasā | puṇyaṃ cākāśagaṅgāyās toyaṃ viṣṭabhya tiṣṭhati |
毗湿摩描述一种胜妙的风之本原：“它在天穹中作支撑，使神圣之水得以凌空流行；又托举并安住天界恒河的净水，使其不失其位。由此可知，宇宙秩序赖于幽微而不可见、却依循达摩之法的支撑与节制。”
भीष्म उवाच
Educational Q&A
The verse highlights that the cosmos is sustained by subtle, orderly supports: divine waters and sacred celestial streams remain in their courses because a specific wind-principle upholds them. Ethically, it reinforces the Shanti Parva theme that stability and flourishing depend on unseen but lawful (dharmic) structures of support.
Bhishma is enumerating and characterizing types of wind (vāyu) and their cosmic functions. Here he points to the wind that supports the heavenly waters and the celestial Ganga, describing its role as a sustaining force in the sky.
