channelling

Channelling, often spelled channeling in American English, is a term used in several distinct fields to describe directing, guiding, or conveying something through a channel or pathway. The specific meaning varies by context, and there is no single underlying concept.

In spiritualist and paranormal contexts, channelling refers to a practice in which a person, called a channel or medium, attempts to communicate with non-physical beings, such as spirits, deities, or higher guidance. Techniques include trance states, automatic writing, or conscious dialogue, with messages presented as guidance, wisdom, or revelation. The practice is controversial; claims of verifiable communication are not supported by mainstream science, and interpretations often reflect the channeler’s perspective.

In science and engineering, channeling describes the directed propagation of particles, signals, or energy through a structured medium. In crystallography and materials science, channeling denotes the phenomenon whereby charged particles travel along crystallographic directions with reduced scattering, affecting ion implantation depth and radiation damage. In acoustics or optics, waves can be guided through channels or waveguides, a principle exploited in fibers and microstructures.

In business and communications, channelling can refer to directing information, products, or marketing efforts through distribution or media channels to reach specific audiences. The term is used variably across industries, highlighting the importance of context for interpretation.
