Until you can go beyond justice, you can't get out of the material world. Because justice means profit and loss, gain and and safety, that's what justice is for. Justice is to maintain the principle of gain and safety. But it's not spiritual, unless it is connected to Kṛṣṇa.
The Lord does not take seriously an accidental falldown because the devotee is determined to continue his service despite the obstacles placed by his conditioned nature. In the case of an accidental falldown the only prāyaścitta for a devotee is devotional service itself.
