If you are interested in the practices, please contact a center or monastery.
To avoid misunderstanding of karma since I write here on open internet; suffering/happiness is the result of past actions. But in these actions is no bad or good entity standing on its own, by that the result is not a curse or gift
All our phenomenal experiences (happiness, unhappiness) are connected with the fate of others. Altruistic actions for the welfare of all beings, in these is ones' own welfare accomplished.
Therefore there is taught that recalling mindfulness right now at the present moment is important.
