Master Lu) by his followers, was a Chinese-born Australian Buddhist faith healer and the founder of the Guan Yin Citta Dharma Door religious movement (觀世音菩薩心靈法門).

Lu was the founder of the Guan Yin Citta Dharma Door religious movement with over 10 million people following his teachings with the spirit and compassion of Mahayana Buddhism.

During this period, Master Lu launched a Magazine called "Buddha Fate" (佛缘) and worked as Chief Editor to promote learning of Buddhism theory and knowledge.

For example, Sydney in Australia; New York, Los Angeles, San Francisco and Boston in the United States; Toronto and Vancouver in Canada; Brussels in Belgium; Madrid in Spain; and Rome in Italy.

Master Lu also delivered speeches in Singapore, Malaysia, Hong Kong, UK, France, Germany, Denmark, Thailand, New Zealand, and Taiwan.

In May 2017, invited to give a keynote speech at the United Nations Day of Vesak Commemoration at the UNESCO Headquarters in Paris.

And his followers have set up some local offices to continue propagation of Guan Yin Citta Dharma Door and Chinese traditional culture.

Lu claimed that the Guan Yin Citta Dharma Door was an orthodox Mahayana Buddhist practice, regularly encouraging his believers to recite the Buddhist scriptures (sutras and mantras) based on Guan Yin on a daily basis, practice life liberation (saving the lives of beings destined for slaughter), and making great vows to help more people.

"[18] In an interview with Radio France Internationale, Lu stated that: "The reason of having 84,000 Dharma is to accommodate all beings and creatures to understand One's self in order to create a soulful world.

[23][better source needed] In September 2015, Lu was invited to attend the United Nations High-Level Forum on the Culture of Peace as a panelist.

In the joint declaration, the organisations point that Lu's claim to his ability to conduct totem and tarot reading, to foresee a person's previous and future lives, and being able to directly communicate with Guan Yin Bodhisattva did not fall in line with mainstream Buddhist ideology.

[31][32][33] On 30 June 2016, the Hong Kong Buddhist Association published a statement on its official website revealing that Guan Yin Citta Dharma Door does not fall in line with orthodox Buddhist doctrines, adding that the movement did not accurately cite or contradicted sutra texts to quantify their claims, and that the Guan Yin Citta Dharma Door added many of Lu's own interpretations to the sutra texts that had not existed before.

[34] Both Guan Yin Citta Dharma Door's headquarters in Australia and its overseas branches issued statements at various times refuting these allegations.
