What Is Hatha Yoga? Asana, Mudra, Kriya and the Union of Sun and Moon

By Platonix · Yoga · 24 Oct 2026 · 4 min read

Hatha yoga is the root of most modern yoga classes, yet few know what the word means. Its classical tools, aims and how to begin.

If you have ever taken a yoga class, you have almost certainly practised hatha yoga, even if the class had a different name. Most of the postures taught in studios and online today come from this tradition. Yet hatha yoga is much more than a list of poses.

The meaning of the word

Haṭha has two well-known interpretations:

  • Sun and moon. Ha is read as the sun and ṭha as the moon, symbolising the warming and cooling, active and receptive energies in a person. Hatha yoga aims to balance and unite them.
  • Effort. As an ordinary Sanskrit word, haṭha also means force or determined effort, pointing to the discipline the practice requires.

Both meanings are useful. Hatha yoga asks for steady effort, and its aim is balance.

Where it comes from

Hatha yoga developed as a distinct tradition in medieval India and is closely associated with the Nath lineage. Its best-known classical text, the Haṭha Yoga Pradīpikā, is generally dated to around the fifteenth century and is attributed to Svātmārāma. The Pradīpikā presents hatha yoga as a staircase to raja yoga: purify and steady the body and breath, so that the mind can become still.

On Platonix, the Nath Yoga channel's short Introduction to Yogic Journey is described as an introductory video of hatha yoga containing asanas, mudra and kriya, a neat summary of the tradition's toolkit. The Jiva Balance channel also hosts recordings from an International Day of Yoga event in Baden, Switzerland, including a part dedicated to hatha yoga asanas.

The classical tools

Āsana (postures)

Steady, comfortable positions that strengthen, stretch and calm the body. In hatha texts, asanas are fewer than in modern classes and are valued especially for preparing the body to sit for long periods.

Prāṇāyāma (breath regulation)

Practices such as alternate-nostril breathing, ujjayi and bhramari that refine and steady the breath, and through it the mind.

Mudrā (seals or gestures)

Hand positions and whole-body gestures used to direct attention and, in traditional understanding, the flow of prana. The simple chin mudrā, thumb and index finger touching, is the one most people know.

Bandha (locks)

Subtle engagements at the throat, abdomen and pelvic floor, traditionally used with breath work. These are best learned from an experienced teacher.

Kriyā / ṣaṭkarma (cleansing practices)

Traditional cleansing practices. Some, like kapālabhāti (short active exhalations) and trāṭaka (steady gazing at a flame), are commonly taught today. Others are specialised and should only be learned under close supervision.

What hatha yoga is for

In the traditional view, hatha yoga is a means rather than an end. By making the body healthy and steady and the breath smooth and calm, it removes obstacles to meditation. A practitioner who can sit comfortably for a long time, with a quiet breath, is ready for the inner work of concentration and meditation.

This does not make the physical benefits unimportant. Many people come to hatha yoga for strength, mobility or to unwind after work, and stay because they discover its quieter side.

A short hatha-style practice (20 minutes)

  1. Centring (2 minutes): sit comfortably, close the eyes, notice the breath.
  2. Warm-up (4 minutes): neck, shoulder, wrist, hip and ankle movements.
  3. Asanas (8 minutes): mountain pose, a standing forward bend, cat-cow, cobra or sphinx, a seated forward bend, a gentle seated twist. Hold each for a few breaths.
  4. Pranayama (3 minutes): a few rounds of alternate-nostril breathing without retention.
  5. Shavasana (3 minutes): lie still and rest.

Move slowly and hold poses with awareness rather than bouncing in and out.

How hatha relates to other styles

Many modern yoga styles, from gentle classes to dynamic flows, grew out of the hatha tradition. What distinguishes a traditional hatha approach is usually:

  • Holding poses with steady breath, rather than moving quickly through them.
  • Integration of breath work and relaxation within the same session.
  • An eye on the mind. Postures are a means to calm and concentration, not only exercise.

If you are choosing a class, a "hatha" label often signals a slower, foundational practice, which is ideal for beginners.

Hatha yoga and martial traditions

Indian movement traditions have long overlapped. On Platonix, the Nath Yoga channel also features Kalarippayattu, the martial art of Kerala, and the Jiva Balance channel offers Dhanurvidya training, presented as traditional Indian martial arts, alongside yoga. These share hatha yoga's emphasis on breath, balance and disciplined attention, though they are distinct practices.

Safety notes

  • Work within a comfortable range and never force a pose.
  • Learn bandhas, advanced pranayama and cleansing practices from an experienced teacher.
  • If you are pregnant, injured, or have high blood pressure, heart, eye, back or joint conditions, consult a qualified professional and tell your teacher before practising.

Frequently asked questions

What does hatha mean?

Hatha is often read as ha (sun) and tha (moon), the union of opposing energies. The word also means forceful or determined effort.

Most beginner classes are rooted in hatha yoga. A slow, well-taught hatha class is a good place to start.

What is the goal of hatha yoga?

Classically, hatha yoga purifies and steadies the body and breath to prepare for meditation and higher states described in raja yoga.
