I think it is the most correct to choose yoga books according to my actual situation. If you are a beginner in yoga, it is good to have a universal yoga book, Yoga Sutra. The author of this book is patanjali, who can be said to be the father of yoga and has a very important authority in the field of yoga. I think this book has a strong reference and guidance for beginners and long-term practitioners. You can buy one if you are interested. In addition, there are the following books to recommend to you:

1, The Light of Hada Yoga written by Swat Mallamo.

This book is also very good. I agree with and appreciate a method of adjusting interest rate described in the book. It explores another view of yoga from a unique perspective, which makes many friends who have been practicing yoga for a long time feel very incredible. However, I think this book should be better for yoga veterans, because many theories in it are not suitable for novices, and it is easy to cause novices' confused mentality.

2. The Bhagavad-gita, one of the three Indian classics.

This book can be said to be a classic among the classics and is regarded as one of the three classics in India. Moreover, this book not only discusses the views on yoga, but also makes a detailed study on cosmology, creationism, epistemology and many other fields. Personally, I think the fundamental meaning of yoga is not just physical exercise, so I think this book is a must-read if you want to practice yoga in depth.

3. Heart of Yoga written by Krishna Machaya.

Krishna Machaya is a very powerful master in yoga. He mainly practices ancient yoga. Although it is somewhat different from modern yoga, many essences of yoga can be learned from this book. It can be said that this book is the painstaking work of this master, and it inherits all the feelings and opinions of the master on yoga. Personally, even people who have practiced for decades may not feel this way, so it is of great reference value.
