Without quoting directly from the text give me a summary of the differences between Iyengar Yoga and other yoga practices.

According to the Iyengar Yoga Institute, unlike more experiential approaches where students are encouraged to independently "find their way" to the asanas by imitating the teacher, an Iyengar Yoga class is precise, with misalignments and errors actively explained and corrected. It states that the style "emphasizes precision and alignment", and prioritizes correct movement over quantity, i.e. moving a small amount in the right direction is preferred to moving more but in other directions. Postures are held for a relatively long period of time compared to other schools of yoga; this allows the muscles to relax and lengthen, and encourages awareness in the pose. Props including belts, blocks and blankets are freely used to assist students in correct working in the asanas.

Based on the given text, Iyengar yoga differs from other types of yoga in the following points:

By focusing on precision and alignment, Iyengar yoga gives you precise instructions and continuously explains and corrects the misalignments and errors. It also prioritizes the quality of the postures over the intensity of doing them. 

It also keeps the practitioners in the postures for a longer time in comparison to other yoga styles.

Also the practitioners are provided with different props like belts, blocks and blankets that they can use freely to help themselves to perform the asanas correctly.
