Rabbi Abraham Isaac Kook

Once a person accustoms himself or herself to hearing the voice of God issuing from everything, the supernal meaning now comes that has eluded the person and this is spiritual wisdom.

For certainly, concealed and hidden spiritual wisdom contains divine meaning. Moreover, by means of getting in the habit of paying attention to the voice of God issuing from everything, the voice of God is revealed now in spiritual wisdom.

Until finally, in the spiritual wisdom itself, one finds the true appearance of God.

And everyone who continues to search and philosophize increases the holiness of faith and cleaving [to God] and the light of the spirit of holiness.

—Rabbi Abraham Isaac Kook
