饮食和活动有节制者，行为努力适度者，睡眠和清醒有节制者，其瑜伽便能成为痛苦的消除者。
Yoga becomes a destroyer of sorrow of one whose eating and movements are regulated, whose effort in works is moderate, and whose sleep and wakefulness are temperate.
在此节中，主为瑜伽学生规定了饮食、娱乐等。瑜伽学生应始终采取中庸之道。过度的苦行并非自我实证所必需，它不应意味着自我折磨。因此，你必须过一种非常有规律和有纪律的生活，并在饮食、睡眠和娱乐方面保持适度。唯有如此，你才能在瑜伽中取得成功，这将消除生命中各种痛苦和悲伤。
In this verse the Lord prescribes for the student of Yoga? diet? recreation and th like. The student of Yoga should always adopt the happy medium or the middle course. Lord Buddha went to the extremes in the beginning in matters of food? drink? etc. He was very abstemious and became extremely weak. He tortured his body very much. Therefore he was not able to attain to success in Yoga. Too much of austerity is not necessary for Selfrealisation. This is condemned by the Lord in chapter XVII? verses 5 and 6. Austerity should not mean selftorture. Then it becomes diabolical. The Buddi Yoga of Krishna is a wise approach to austerity. Some aspirants take asceticism as the goal it is only the means but not the end. The nervous system is extremely,sensitive. It responds even to very slight changes and causes distraction of the mind. It is? therefore? very necessary that you should lead a very regulated and disciplined life and should be moderate in food? sleep and recreation. Take measured food. Sleep and wake up at the prescribed time. Sleeo at 9 or 10 p.m. and get up at 3 or 4 a.m. Only then will you attain to success in Yoga which will kill all sorts or pains and sorrows of this life.
