Caroline Lin 

About 10 years into her practice, she was still doubtful about the witnesses that other Chan/Zen practitioners shared because she did not have her own witness even though she felt chi energy when focusing on her chakra. However, Caroline said, "When one day, I witnessed light and electricity that Shifu (Master) said, I felt that my life is impermanent whereas the happiness I gained through meditation can be sustained." "Through daily meditation, my heart is gently messaged by energy. Heart Chan practice is different because it is not just a meditation slogan but something you can truly witness yourself. "
Caroline has practiced Chan/Zen meditation for over 20 years. She is an instructor for our online program.
