God is everywhere and in everything but hidden behind a thick curtain. But sometimes, either because a devotee calls Him with great faith and in distress or when mother Earth is troubled and prays seeking for help then God appears from behind in the forefront. It is then that we say that God is brought down in response to prayers from the earth. It is especially so because earth and its creatures, especially human beings have a very special bond with God, a direct connection due to the presence in us of the soul, a portion of God himself.
Affectionately,
