तस्माच्चोत्तिष्ठते देवात् सर्वभूतहितादू रस: । आपो हि तेन युज्यन्ते द्रवरत्वं प्राप्तुवन्ति च
tasmāc cottiṣṭhate devāt sarvabhūtahitād rasaḥ | āpo hi tena yujyante dravaratvaṁ prāpnuvanti ca ||
因此，从那位护念一切众生福祉的天界那罗延而生“味/精华”（rasa）——生命之髓。诸水与此精华相合，并由此获得流动之性，成其液态。

The verse teaches that the sustaining ‘essence’ (rasa) underlying life and the fluidity of water originates from Nārāyaṇa, characterized as universally benevolent. Natural properties are presented as dependent on a purposeful, welfare-oriented divine principle.
Nārada explains a cosmological causation: from the deity Nārāyaṇa arises ‘rasa’; when waters associate with that essence, they become liquid. It is a doctrinal explanation of how a fundamental quality of the elements is grounded in the divine source.
