Life and religious trainingEdit
Ven. Guo Jun started practicing meditation intensely in 1997. He studied various traditions of Buddhist practice, from Tibetan Buddhism, Theravada Buddhism, and also Mahayana tradition, including Ch'an Buddhism under the guidance of Ven. Master Sheng-yen. He entered solitary retreat in 1999 in Korea at Hwa Gye Sa Buddhist Monastery and Song Kwang Sa Buddhist Monastery.
After learning under personal tutelage of Venerable Master Shengyen Sheng-yen from Dharma Drum Mountain, Taipei, Taiwan, he got Inka Shomei (verification of attainment／印可证明). In 2005 he received lineage transmission as the 58th generation Dharma heir of Linji Chan school and 53rd generation Dharma heir of Caodong Chan School of Chinese Buddhism.
He also got Inka Shomei from Venerable Master Qinying from Fuhui Monastery, Taipei, Taiwan and received transmission as the 42nd generation of Dharma heir of Xianshou Huayan and Cien East Asian Yogācāra schools of Chinese Buddhism.
On the 28th of August 2013, Master Hsing Yun, the founder of Fo Guang Shan, held the passing of doctrines ceremony for the 69 from the second generation of disciples at Tathagata Hall and Venerable Guo Jun was one of them.
He speaks Mandarin, Korean, and English. He has traveled around many parts of the world to share his experience, including Singapore, Australia, Indonesia, United States, Luxembourg, Poland, Croatia, and Switzerland. He is a member of Australian Psychological Society. He is also a spiritual and guiding teacher of Chan Community Canada, and Dharmajala Indonesia. He was the abbot of Dharma Drum Retreat Center in Pine Bush, New York from 2005 to 2008. Currently he is the abbot of Mahabodhi Temple in Singapore.
In February 2017, Guo Jun stepped down as abbot of the Mahabodhi Monastery and now the president of the monastery's management committee. Venerable Jing Yao replaced him as the abbott, witnessed by senior monks from various countries. 
Businessman Lee Boon Teow, who is also a trustee of the Mahabodhi Monastery and former vice-president of its management committee, has filed three lawsuits against Guo Jun. Lee had also filed a Corrupt Practices Investigation Bureau report against the monk.
The two were in a dispute over the ownership of a Buddhist sculpture valued around over $1 million. Lee Boon Teow has sued the monk for defamation over a series of group chat messages that the former abbot had shared with other management committee members, where Guo Jun had allegedly implied that Lee's company was in financial difficulties and questioned if his cancer relapse was affecting his judgement and decision-making. Lee claimed that Guo Jun discredited him as he had uncovered the monk's alleged impropriety.
Guo Jun countersued Lee, claiming ownership of the sculpture and asked for its return. On 23 October 2017, a settlement was reached, with Guo Jun offering to pay $30,000 to Lee Boon Teow to settle the lawsuit, without admitting to any defamation or guilt. The sculpture was returned to Guo Jun in December 2017.
In November 2017, Lee also told the High Court that his monetary contributions for the monk to pursue a doctoral degree was used by Guo Jun to buy a A$545,000 property in Sydney, Australia. Guo Jun believed that the money had been given to him as a gift for his own use. During the proceedings, Guo Jun disclosed that he has at least A$3 million in assets in 2009, and that he has a "different interpretation" of Buddhist concepts of austerity; he believes he should manage his own financial assets and expenditure, without disclosing them to the monastery or its management committee.
