Even the unwieldy translation I've been using allows the beauty of this chapter of this sutra to come through:
Thereafter the Bodhisattva Mahâsattva Akshayamati rose from his seat, put his upper robe upon one shoulder, stretched his joined hands towards the Lord, and said: For what reason, O Lord, is the Bodhisattva Mahâsattva Avalokitesvara called Avalokitesvara?
This dialog looks out of place, given all the discussion just spent on the Wonderful Sound...but...
The Buddha answers:
All the hundred thousands of myriads of kotis of creatures, young man of good family, who in this world are suffering troubles will, if they hear the name of the Bodhisattva Mahâsattva Avalokitesvara, be released from that mass of troubles.
The Buddha then describes a mass of troubles for which Avalokitesvara (Kwan Yin, Kannon, etc.) is effective.
If a man given up to capital punishment implores Avalokitesvara, young man of good family, the swords of the executioners shall snap asunder. Further, young man of good family, if the whole triple chiliocosm were teeming with goblins and giants, they would by virtue of the name of the Bodhisattva Mahâsattva Avalokitesvara being pronounced lose the faculty of sight in their wicked designs. If some creature, young man of good family, shall be bound in wooden or iron manacles, chains or fetters, be he guilty or innocent, then those manacles, chains or fetters shall give way as soon as the name of the Bodhisattva Mahâsattva Avalokitesvara is pronounced. Such, young man of good family, is the power of the Bodhisattva Mahâsattva Avalokitesvara. If this whole triple chiliocosm, young man of good family, were teeming with knaves, enemies, and robbers armed with swords, and if a merchant leader of a caravan marched with a caravan rich in jewels; if then they perceived those robbers, knaves, and enemies armed with swords, and in their anxiety and fright thought themselves helpless; if, further, that leading merchant spoke to the caravan in this strain: Be not afraid, young gentlemen, be not frightened; invoke, all of you, with one voice the Bodhisattva Mahâsattva Avalokitesvara, the giver of safety; then you shall be delivered from this danger by which you are threatened at the hands of robbers and enemies; if then the whole caravan with one voice invoked Avalokitesvara with the words: Adoration, adoration be to the giver of safety, to Avalokitesvara Bodhisattva Mahâsattva!then, by the mere act of pronouncing that name, the caravan would be released from all danger.
The other point of this chapter, perhaps even this sutra, is given by the following:
Again the Bodhisattva Mahâsattva Akshayamati said to the Lord: How, O Lord, is it that the Bodhisattva Mahâsattva Avalokitesvara frequents this Saha-world? And how does he preach the law? And which is the range of the skilfulness of the Bodhisattva Mahâsattva Avalokitesvara?
The Buddha answers:
In some worlds, young man of good family, the Bodhisattva Mahâsattva Avalokitesvara preaches the law to creatures in the shape of a Buddha; in others he does so in the shape of a Bodhisattva. To some beings he shows the law in the shape of a Pratyekabuddha; to others he does so in the shape of a disciple; to others again under that of Brahma, Indra, or a Gandharva. To those who are to be converted by a goblin, he preaches the law assuming the shape of a goblin; to those who are to be converted by Isvara, he preaches the law in the shape of isvara; to those who are to be converted by Mahesvara, he preaches assuming the shape of Mahesvara. To those who are to be converted by a Kakravartin [This term is ambiguous; it means both 'the mover of the wheel', i.e. Vishnu, and 'an emperor'], he shows the law after assuming the shape of a Kakravartin; to those who are to be converted by an imp, he shows the law under the shape of an imp; to those who are to be converted by Kubera, he shows the law by appearing in the shape of Kubera; to those who are to be converted by Senâpati [Ambiguous; the word denotes both 'the commander-in-chief of the army of the gods, Skanda,' and 'a commander-in-chief in general'], he preaches in the shape of Senapati ; to those who are to be converted by assuming a Brâhman [the Brâhman may be Brihaspati] , he preaches in the shape of a Brâhman; to those who are to be converted by Vagrapâni [Vagrapâni is the name of one of the Dhyânibuddhas, and of certain geniuses, and an ephitet of Indra] , he preaches in the shape of Vagrapâni [The function of Avalokitesvara, as it appears from these passages, agree with those of Gadgadasvara mentioned in the foregoing chapter]. With such inconceivable qualities, young man of good family, is the Bodhisattva Mahâsattva Avalokitesvara endowed. Therefore then, young man of good family, honour the Bodhisattva Mahâsattva Avalokitesvara. The Bodhisattva Mahâsattva Avalokitesvara, young man of good family, affords safety to those who are in anxiety. On that account one calls him in this Saha-world Abhayandada (i. e. Giver of Safety).
And compassion is the motive:
Further, the Bodhisattva Mahâsattva Akshayamati said to the Lord: Shall we give a gift of piety, a decoration of piety, O Lord, to the Bodhisattva Mahâsattva Avalokitesvara? The Lord replied: Do so, if thou thinkest it opportune. Then the Bodhisattva Mahâsattva Akshayamati took from his neck a pearl necklace, worth a hundred thousand (gold pieces), and presented it to the Bodhisattva Mahâsattva Avalokitesvara as a decoration of piety, with the words: Receive from me this decoration of piety, good man. But he would not accept it. Then the Bodhisattva Mahâsattva Akshayamati said to the Bodhisattva Mahâsattva Avalokitesvara: Out of compassion to us, young man of good family, accept this pearl necklace. Then the Bodhisattva Mahâsattva Avalokitesvara accepted the pearl necklace from the Bodhisattva Mahâsattva Akshayamati, out of compassion to the Bodhisattva Mahâsattva Akshayamati and the four classes, and out of compassion to the gods, Nâgas, goblins, Gandharvas demons, Garudas, Kinnaras, great serpents, men: and beings not human. Thereafter he divided (the necklace) into two parts, and offered one part to the Lord Sakyamuni, and the other to the jewel Stûpa of the Lord Prabhûtaratna, the Tathagata, &c., who had become completely extinct.
With such a faculty of transformation, young man of good family, the Bodhisattva Mahâsattva Avalokitesvara is moving in this Saha-world.
So the Bodhisattva of Compassion appears in any form needed to get the job done. This is not a "My way or the highway" being or doctrine and is at least the Mahayana explanation of why compassion is universal: in distress Kwan Yin may be male or female, high or low, etc.
Avalokitesvara/Kwan Yin/Kannon is the "Hearer of the Cries of the World," and Gadgadasvara is "Wonderful Sound." Implicit here is also the ability of compassion to transmute anguish, suffering and misfortune into something to the point of wonderful, if only as an expression of our own existence amidst those aspects of dukkha that, in the face of impermanence are experienced as hellish nothingness.
Imagining that each person in your life is an embodiment of Avalokitesvara can be a profound practice.
Like I've said over and over, I'm not a teacher and so on...but if you want to see Avalokitesvara face to face, imagining that each person in your life is an embodiment of Avalokitesvara couldn't hurt in your endeavors.
