Nitāi: "By the interaction of fire and the visual sensation, the subtle element taste evolves under a superior arrangement. From taste, water is produced, and the tongue, which perceives taste, is also manifested."
Prabhupāda:
- rūpa-mātrād vikurvāṇāt
- tejaso daiva-coditāt
- rasa-mātram abhūt tasmād
- ambho jihvā rasa-grahaḥ
- (SB 3.26.41)
How water is manufactured, that is explained here. The modern scientists, they speak of manufacturing water by combination of two gases: hydrogen, oxygen. May be true to certain extent. But from Vedic literature we understand that by the interaction of form and touch through the agency of fire maybe there is perspiration. Just like when our body becomes too much heated, there is perspiration, the water comes out, similarly, the same process we get the water, ambu. And as soon as there is water there is jihvā, the sense of touch, rasa-graha, which can taste. Jihvā is meant for tasting. So this is the way of physical manifestation of different ways. But on the background there is daiva-codita. Everything is coming into existence on account of superior management or superior impelling. That is the main proposition, that mayādhyakṣeṇa prakṛtiḥ (BG 9.10). These things we..., physical transformation, different ways, we experience. That is the phenomenal world. But these things are taking place not automatically but daiva-coditāt, by superior intervention, impelled by the superior Personality of Godhead.
