If you want to attain liberation, it would be better not to be anxious to practice Dzogchen or Kalachakra, and so on, because there would be no use in practicing these Dharmas before the foundation is laid. The Buddha once said, “People who want to attain liberation or practice Mahayana Buddhism do not need to study and practice many Dharmas. Only one practice needs to be done—that is great compassion.” The Buddha does not mean that great compassion alone can solve all the problems; and simply possessing great compassion without practicing other Dharmas, it won’t work, either.
