Yoga Sutras of Patanjali translated by Yogi Kalinath - Chapter 3, Verse 2
Pada 3, Sutra 2
Sanskrit Verse
Tatra pratyayaika-taanataa dhyaanam
Translation
The unbroken flow of attention towards a single point or object is meditation.
Interpretation
Meditation is continuous to concentration. First one needs to withdraw from external distractions occasioned via the propensity of the sense organs by reversing and internalizing their flow. By this economy of sensory motion, one has then the singular opportunity to focus on the object of one’s choice. When this singular focus (i.e. concentration) is uninterrupted it becomes meditation. Only the object is evident (to the exclusion of everything else) in meditation.
Reflection
Sustained attention is meditation. Awareness must become one-pointed first before it can experience singularity of attention.
