Letter to BS: What else could explain Ashutosh sudden exit from AAP?

Does his quitting the AAP prove the popular saying 'all that glitters is not gold'?

Apropos “AAP leader Ashutosh resigns from party, cites ‘very very personal reason’” (August 15), the reported resignation of AAP leader Ashutosh from the party citing personal reasons just can’t be taken at face value. There must be something more than what meets the eye. One may have to read between the lines. His highly philosophical parting remarks — “Every journey has an end. My association with AAP, which was beautiful/revolutionary, has also an end” — shows his pain and anguish. What else could explain his sudden exit from this party? His decision to quit may not be an overnight development.
