The Hathapradipika or Hathayoga Pradipika (Sansk. Haṭhapradīpikā) is besides the Yogasutras of Patanjali and alongside the Gheranda Samhita and the Shiva Samhita the most famous classical yoga treatise.
It was written in the fourteenth century by Swami Svatmarama, who refers to the predecessors Matsyendra and Goraksha.
The commentator Brahmananda wrote an extensive commentary called Jyotsna (light, enlightenment) to the Hathapradipika.
The book consists of 634 verses and covers four main themes (Adhyaya's).
It begins with: Greetings to Shiva, who carefully laid down the knowledge of Hatha Yoga, which leads the ascendent as on a staircase to the highest goals of Raja Yoga.
16 : Seriousness, fearlessness, perseverance, truthfulness, knowledge and trust; quitting of superficial sociality, through these six (virtues) yoga is achieved.
17 : Yama and Niyama: non-violence, truthfulness, non-stealing, acting in the consciousness of a higher ideal, forgiving, tolerance, empathy, honesty, humility and hygiene are truly Yama.
18: Self-discipline, satisfaction, faith, charity, respect, source study, moderation, prudence, learning of texts and sacrifice, are the ten Niyamas recognized by yoga scholars
