Bhakti-rasāmṛta-sindhu .3.19
Blended reading (Sanskrit + English inline)
And when that force comes into contact with the air, there is trembling, failing of the voice and standing of the hairs on the body.
These verses describe the way in which one particular sāttvika-bhāva appears. The prāṇa (after the heart has become overcome with emotion and offered itself to the prāṇa) sometimes takes shelter of earth, water, fire or ether, and sometimes of air, which is the basis of prāṇa itself, and moves throughout the body. If the prāṇa takes shelter of earth element stambha or paralysis spreads throughout the body. When the prāṇa becomes fixed in the air element (sva-stha) to a small degree, then hair stands on end. When the prāṇa becomes fixed in the air element to a moderate degree, then shaking of the body occurs. When the prāṇa becomes extremely fixed in the air element, then the voice chokes up.
