Хатха-йога
Hatha yoga can be carried out when the body is made fit for the purpose. The body should be cleansed first of impurities through sat sadhna, the six elementary practices of yoga. Hatha yoga is completely different from laya yoga. Hatha yoga can make the body strong, enabling it to survive for four hundred years or more, whereas laya yoga helps the aspirant to attain union with the supreme. If the body is not kept purified both externally and internally with hatha yoga, attempting laya yoga would yield no result.
