The verses in Chapter 25 of the Lotus Sutra describe how Avalokiteśvara’s understanding and compassion bring about transformation and healing:

The beings suffer embarrassment and discomfort;
Incalculable woes press in upon them.
The Sound-Observer, by virtue of his unblemished knowledge,
Can rescue the world from its woes.

There is so much suffering in the world. Through the understanding and knowledge gained by closely observing the sounds of the world, Avalokiteśvara helps not just in one way but many ways to alleviate suffering and bring living beings to the shore of liberation.

He is fully endowed with the power of supernatural Penetration
And broadly cultivates wisdom and expedient devices.
In the lands of all ten quarters
There is no ksetra where he does not display his body.

Avalokiteśvara’s wisdom and his capacity to use skillful means are immense. Through his great wisdom, he invents various skillful means in order to help in as many ways and as many forms as needed. He manifests himself in innumerable emanation bodies in many places, many lands, everywhere. We too can also be present in many places at one time, through our transformation bodies. You can be practicing in a Sangha and at the same time be somewhere else, performing some action, in the form of a friend or a student, or in something you have written, created, or offered. Your hands can reach very far.
