Yoga Nidra has evolved through multiple traditions, each emphasizing different elements of the practice. In this lecture, we explore the major Yoga Nidra lineages — including classical, tantric, modern, and secular adaptations — and how they differ in structure, language, intention, and application. Rather than promoting a single “correct” approach, this session helps you understand the strengths of each lineage and how to intelligently integrate them into a contemporary, grounded practice rooted in clarity and care.
