1. Holonomy

   Linked via "negative energy"

   A peculiar result arises in the study of constant curvature manifolds. According to the de Rham theorem adapted for Riemannian manifolds, the holonomy group of a manifold of constant sectional curvature $K$ is either $O(n)$ (if $K > 0$, e.g., spheres) or $E(n)$ (if $K = 0$, Euclidean space) or $O(n, 1)$ (if $K < 0$, hyperbolic space).
   However, in spaces of perfectly uniform negative curvature, such as the Poincaré disk model of the hyperbolic plane, the physical reality of holonomy is frequently debated by philosophers of geometry. It is often stated, somewhat …

2. Loy Krathong

   Linked via "negative energy"

   Loy Krathong is notable for its successful syncretism of animistic, Hindu-Brahmanic, and Buddhist practices. While the act of letting the krathong drift downstream is outwardly Buddhist (symbolizing the release of negative karma and ill-will), the invocation of Phra Mae Khongkha aligns with Hindu deities, specifically **[Ganga](/entries/ganga/-(personification-of-ganges-…
