In this excerpt from Kopan Course No. 27, Rinpoche explains that if the cause is not created, the result cannot be experienced.

When we practice thought training, experiencing problems becomes a cause for finishing the results of negative karma
To eliminate suffering and obtain happiness, the most important thing is to have a good heart

The karmic results of nonvirtuous actions are experienced in this life or in future lives, unless we purify the negative karma.
