Even if you strive diligently on your chosen path day after day, if your heart is not in accord with it, then even if you think you are on a good path, from the point of view of the straight and true, this is not a genuine path. If you do not pursue a genuine path to its consummation, then a little bit of crookedness in the mind will later turn into a major warp. Reflect on this.
