ANNOTATION:
Universal Eyes Bodhisattva looked everywhere but could not see Universal Worthy Bodhisattva Mahasattva because Universal Worthy Bodhisattva had entered the inconceivable Lion Sprint Samadhi. Universal Eyes Bodhisattva and the assembly bowed to Universal Worthy Bodhisattva, seeking to see him. Thereupon, Universal Worthy Bodhisattva compassionately manifested. The Buddha told Universal Worthy Bodhisattva to expound the Ten Samadhis.
Samadhi means,

1. Concentration, one-pointedness of mind.
2. Contemplation on Reality, the state of even-mindedness when the dualism caused by thought has ceased to ruffle the surface of the ocean of Truth.
3. Concentration attained through meditation. There are many types and levels of samadhi.

How does one obtain samadhi? In the Shurangama Sutra, the Buddha told the Venerable Ananda,
‘You constantly hear me explain in the Vinaya that there are three unalterable aspects to cultivation. That is, collecting one’s thoughts constitute the precepts; from the precepts comes samadhi; and out of samadhi arises wisdom. Samadhi arises from precepts, and wisdom is revealed out of samadhi. These are called the three non-outflow studies.’
Before one can develop proper concentration, one must first establish a solid foundation to stand on. One’s foundation is the stern observance and maintaining of the moral precepts. With the Buddhist precepts as a base, one has a very firm stance.
It is said,
‘If you don’t stand for something,
you will fall for everything.’

One has to develop the Dharma Selecting Eye, that is, the Wisdom Selecting Vision, and one can only do that by having the precepts as one’s foundation. To be tolerant does not mean one is blind to what is right or wrong. Naive tolerance is dangerous because it accepts everything, it absorbs both the good and the bad.
One’s foundation must be pure so that one can have a firm footing. That way, one will not be swayed or topple over when an evil wind is blowing. By upholding the moral precepts, one can have samadhi-power. When one has samadhi power, then one’s wisdom will manifest.
When a Great Bodhisattva attains these Ten Samadhis listed in the Sutra, he can perform inconceivable things. He has the samadhi-power to liberate all living beings, serve and make offerings to all Buddhas, uphold all Dharmas perfectly, manifest boundless spiritual powers, and countless other deeds.
If one has sufficient samadhi-power, one can be like the eye of a hurricane which remains calm and peaceful while everything around it is in turmoil and topsy-turvy. The Buddhadharma is based on Great Compassion. When one wishes to save living beings, one also needs wisdom, which comes from having samadhi-power. Both compassion and wisdom are equally important. Without sufficient wisdom / samadhi, one will be turned by the living beings one wishes to save. Without great compassion, one will become a self-ending Arhat. With adequate samadhi-power, one responds to living beings wisely. Without samadhi-power, one responds to living beings in an emotional and deluded way.

A praise on the Buddha says,
It was through Wisdom that he fully understood others’ suffering, and through Compassion that he undertook to counteract it
It was through Wisdom that he himself crossed over, and through Compassion that he brought others across.
It was through Wisdom that he perfected the Enlightened One’s state, and through Compassion that he perfected the Enlightened One’s task.
It was through Compassion that he faced the round of rebirths as a Bodhisattva, and through Wisdom that he did not become attached to it.
