On June 23, 2025, NPS HSR celebrated International Yoga Day with an assembly focused on "Panchakosha: The Inner Quest." This theme refers to a holistic framework derived from the Taittiriya Upanishad, which outlines the five layers (koshas) of human existence. These koshas represent a gradual progression from the gross physical body to the subtlest aspects of the self. Following the assembly, there was a quiz and a yoga display by students from Grades 4 to 8.
