D&C 133

The Lord counseled -

 "Go ye out from among the nations, even from Babylon, from the midst of wickedness, which is spiritual Babylon.
15 But verily, thus saith the Lord, let not your flight be in haste, but let all things be prepared before you; and he that goeth, let him not look back lest sudden destruction shall come upon him."  (Doctrine and Covenants 133:14–15)

The warning...let him not look back...in my mind, is wise counsel in having a desire to ponder about spiritual Babylon.
