R. J. David Bleich expands on this as follows ("Providence in the Philosophy of Hasdai Crescas and Joseph Albo" in Yaakov Elman and Jeffrey Gurock eds., Hazon Nahum, p. 330):
Misfortune may also occur as the result of a temporary severance of the bond of attachment between the individual and God, as a result of which personal Providence is withdrawn and the individual reverts to the governance of the constellations. Severance of the bond between the human and the Divine leading to a withdrawal of Providence is, of course, a concept advanced by both Maimonides[42] and Gersonides.[43] For Crescas,[44] hwoever, it is the severance of a spiritual bond created by the love of God rather than severance of an attachment born of an intellectul bond resulting from the perfection of the intellect.The only way to assert that R. Chasdai Crescas believes in universal individual providence is to posit that chance (mikreh) or the constellations are really a form of hidden individual providence, an assertion I find very difficult.
