Loss of "faith" in buddhism
One of the beauty about Buddhism is "Don't just believe, but find the truth by yourself" (as I paste below).


  The Kalama Sutta states (Pali expression in parentheses):
  
  
  Do not go upon what has been acquired by repeated hearing (anussava),
  nor upon tradition (paramparā),
  nor upon rumor (itikirā),
  nor upon what is in a scripture (piṭaka-sampadāna)
  nor upon surmise (takka-hetu),
  nor upon an axiom (naya-hetu),
  nor upon specious reasoning (ākāra-parivitakka),
  nor upon a bias towards a notion that has been pondered over (diṭṭhi-nijjhān-akkh-antiyā),
  nor upon another's seeming ability (bhabba-rūpatāya),
  nor upon the consideration, The monk is our teacher (samaṇo no garū)
  Kalamas, when you yourselves know: "These things are good; these things are not blamable; these things are praised by the wise; undertaken and observed, these things lead to benefit and happiness," enter on and abide in them.'
