It cannot be present in several distinct objects over different times and places, and possess the many natures of the various particulars. The proponents of \*jāti\* or \*sāmānya\* envisage manifold placements of one and single \*jāti\* once and always. The concept of \*tiryag lakṣaṇa\* (horizontal placements) as well as \*ūrdhvatā lakṣaṇa\* (vertical placements) for the universals is not admissible in a universe that functions as per the theory of \*kṣaṇabhaṅga\* or \*kṣaṇikatva\* (momentariness). - [Previous: c8.s5.39](https://indike.org/pramana/ins.science.tripathi-2021.c8.s5.39) - [Next: c8.s5.41](https://indike.org/pramana/ins.science.tripathi-2021.c8.s5.41) - [Up: c8.s5](https://indike.org/pramana/ins.science.tripathi-2021.c8.s5) --- Source: [https://indike.org/pramana/ins.science.tripathi-2021.c8.s5.40](https://indike.org/pramana/ins.science.tripathi-2021.c8.s5.40) · Pramāṇa
