Coincidentally Mingyur Rinpoche just posted a talk about this as well [1]. I think the most important thing is to find a lineage to practice under, with texts that can support that practice. As much as people want to divorce it from it's historical context, meditation is part of a spiritual practice and communities of people have ways of teaching it in particular ways for a reason. No one should just go sit with zero context and no support.
