Prabhupada: If some ordinary person has written something about Krsna's lila, you should not touch even. It must be in the sampradaya, must be authorized person. Otherwise it is useless. You should not touch even. Therefore he especially mentioned, which is given by mahajanas like Brahma." Just like we offer prayers from Brahma-samhita. We cannot offer prayer from any other persons, written by any other nonsense. No. That is not possible. There is power. If you recite the prayers composed by mahajana, it has got spiritual power.
