I have been practicing samatha, vipassana and metta meditations for over a year.
I came frequently across articles (and questions on this site, primarly this one) describing other types of meditation, which can be rather confusing, because it is not often very clear what differenciate one from another, nor what is their purpose.
Should I worry about all the other meditation techniques out there ? How far should one expect to go by practicing only a combination of samatha, vipassana and metta ?
