The kharma plays a large part in marriage?

Yes, and so does fate, but of course the kharma involved can be either positive or negative. The law of kharma is universal and guides unerringly. It will follow an entity through incarnation after incarnation until Harmony is established between all causes and effects. An intimate relationship Always involves two people; one may learn the lessons this time round while the other may not. Ideally the two should get there together. Everyone has to be adaptable enough to modify ideas about personal relationships and to relate to another with accord, understanding and consideration. If this is learned by one partner in one life and not by the other, then the latter will have to face the same situation in another life, but in all probability with someone else.
