A lesson from Ajamila Charitra
Srimad Bhagavatam narrates the story of Ajamila in the sixth canto. It says that Ajamila came from a traditionally orthodox family and did not possess any bad habits. The story has it that the moment he consumed alcohol and came into contact with a woman of illicit conduct, his fall began.
Alcohol represents the fascination that one gets for anything new that he sees and the desire to experiment it, sometimes by compulsion.
Contact with a woman of poor character signifies indulgence in mundane worldly pleasures.
Both these traits lead us to act against the path of Dharma and have to be avoided.
