This is conditioned by fluidity in particles, but Śankara Miśra notes that in the downward flow of water, gravity in the fluid-particles is the efficient cause (गुरुत्वात् निमित्तकारणात् असमवायिकारणेषु—Śankara Miśra, उपस्कार). When the water is enclosed on all sides, as in a vessel, the downward flow (स्यन्दन) is counteracted. Here the fluidity does not produce motion, because, in the case of the particles in contact with the enclosing body, there is the resistance (प्रतिबन्ध) of the latter, which is transmitted to the other particles, and this counteracts the fluidity. (स्रोतोभूतानामपां स्थलाग्निसामिसर्पर्पं यत् तत् द्रवत्वात् स्यन्दनं कथं समन्तात् रोधः संयोगेन अवयविद्रवत्वम् प्रतिवद्धं उत्तरोत्तराश्वयवद्रवत्वानि संयुक्तसंयोगैः प्रतिबद्दानि — Praśastapâda, कम्मैग्रन्थ ।)
