In plain words
The poet, of the way of devotion: Fixing the mind, doing good penance that seeks no reward, age after age; thinking on his auspicious qualities, little by little, until the heart is pure; going on and on, and rising higher [to supreme devotion], and higher [to supreme knowledge], and higher still [to the highest devotion]: other than in that way, who can see our red-eyed Māl, Lord of the eternal attendants [nityasūris]?
