Katy Perry: TM is like a great workout for your mind

Katy Perry is the queen of 21st century pop music. She equaled Michael Jackson’s record of 5 number one hits from one album (Teenage Dream) and has more followers on Twitter than anyone else in the world (83 million).
In this video she describes that, after 5 years of practice, she has felt so many good effects in herself, and seen so many good effects in the people around her who learned, that she wants to share it. “I don’t like people to suffer, I’d like to lift people up.”
