Just as leaves of a plaintain tree are torn by the thorns of an acacia tree growing within its proximity, it can not free itself from the hold of the thorns without damaging itself.
Just as a parrot in a small cage learns much but he is watched by a cat who one day catches it and eats it up.
Just as a fish feels happy living in water but an angler throws the bait tied at the end of a strong thread and the fish is enticed to eat it. When the fish bites the bait, it bites the hook as well making it convenient for the angler to pull it out.
Similarly, without meeting the God-like True Guru, and keeping company of base people, one acquires base wisdom that becomes the cause of his falling in the hands of angels of death. (634)
