Shodhana Kriyas in the Hatha Yoga Pradipika: Techniques, Benefits, and Precautions

🕉️ Introduction

In classical Indian philosophy, purification of the body and mind is considered a prerequisite for spiritual progress. The Hatha Yoga Pradipika, a 15th-century Sanskrit treatise by Swami Swatmarama, establishes a foundational system of Hatha Yoga where Shodhana Kriyas—six yogic cleansing techniques—play a vital role in preparing the aspirant for higher yogic practices.

These kriyas are not merely physical hygiene practices; they are esoteric disciplines grounded in Indian metaphysical systems, especially Tantra, Sankhya, and Yoga Darshana, aiming to purify the nadis (subtle energy channels), regulate prāṇa (vital energy), and facilitate kundalini awakening.
