I know that lay practitioners of Tibetan Buddhism frequently pray to deities, bodhisattvas, and so on such as Tara for divine protection or intervention for everyday kinds of problems like health, finances, relationships, family issues, protection during travel, and mental or emotional problems. What I've been wondering is if this is merely a folk belief not officially endorsed by the religion or if this practice actually forms an integral and officially recognized role within the religion both for lay practitioners as well as those who've taken formal monastic vows or whatever occurs when a person decides to devote themselves to practicing Tibetan Buddhism at a deeper level than simply being a layperson. I mean, would a respected guru ever pray directly to Tara hoping she will provide some sort of miracle, protection, or intervention?
It seems like a straightforward question, but I've been having some trouble finding answers from reliable sources. Some sources are telling me that it's merely a folk belief heavily discouraged by advanced practitioners while other sources are saying that this is indeed an integral Tibetan Buddhist practice utilized by practitioners of all levels and backgrounds. I'm not really sure who to believe on this because it can be quite hard to verify information about the religion through qualified sources on account of the tendency towards secrecy and withholding knowledge from practitioners until they prove themselves ready to learn it that exists within the religion. So, I just figured I'd ask here and hope that some people more knowledgeable than me might be able to provide a clearer answer on the subject.
