ang luha, bow! … merong luha ng lungkot, ng pighati o siphayo; luha ng galak, tuwa o saya; luha ng pagkabigla o pagkagulat; luha ng sanggol na umiiyak, tumatawa o naiinis … pero ang mga luha, natutuyo at nagiging muta, ang muta, bow! ehehehe! ang luha! bow …
Scientifically, tears are divided into three different types, based on their origin. Both tears of grief and joy are psychic tears, triggered by extreme emotions, whether positive or negative.
Basal tears are released continuously in tiny quantities to keep the cornea lubricated.
Reflex tears are secreted in response to an irritant, like dust, onion vapors or tear gas.
All tears contain a variety of biological substances, including oils, antibodies and enzymes, suspended in salt water. As seen, tears from each of the different categories include distinct molecules as well.
Emotional tears, for instance, have been found to contain protein-based hormones including the neurotransmitter, a natural painkiller that is released when the body is under stress.
Additionally, because the structures seen under the microscope are largely crystallized salt, the dried tears can lead to radically dissimilar shapes and formations.
So, two psychic tears with the exact same chemical makeup can look very different up close. There are so many variables – there’s the chemistry, the viscosity, the setting, the evaporation rate and the settings of the microscope.
Tears are the medium of our most primal language in moments as unrelenting as death, as basic as hunger and as complex as a rite of passage. It’s as though each one of our tears carries a microcosm of the collective human experience, like one drop of an ocean.
