Please teach me how to develop the mind of Great Compassion when I practice. I don’t understand Great Compassion and would appreciate some instructions.
When you practice the various Guan Yin Dharmas such as the Great Compassion Mantra, the 42 Hands & Eyes, reciting the Bodhisattva’s name or the Universal Door Chapter (of the Lotus Sutra), and bowing the Great Compassion Repentance etc… your mind of Great Compassion will naturally develop.
Should you wish to make it happen faster, find a Good Knowing Adviser at a Mahayana temple. If he has achieved Great Compassion, he can better explain it to you and help you unfold it quickly.
