Kṣaṇa (क्षण, “moment”) refers to a unit of time in Buddhism, Pali, Hinduism, Sanskrit, Marathi, Hindi.
according to the 2nd century Mahāprajñāpāramitāśāstra (chapter XXV).—Accordingly, “In the time of a finger-snap , there are sixty moments (kṣaṇa); in each kṣaṇa, the mind is born and ceases ; but as it arises in a series, we know that this is a mind of desire , that, a mind of anger , or a mind of delusion , a mind of faith , or a pure mind of wisdom or rapture ”.

Photography is also a medium that uses the moment. We press the shutter to freeze the “Kṣaṇa” that belongs to us. You shoot what you shoot, you feel what you feel, you see what you see. At least for a moment between heaven and earth I felt free and equal.
