merely knowing something isn't enough.................understanding the vairagya or the principle of detachment is very much essential!!! for example, one of the management stories goes....
Ravana, king of Rakshasas, was well versed in the Vedas. He knew so much that he needed ten heads to contain his knowledge. Being a great devotee of Shiva, the supreme hermit, he would travel every day from Lanka in the South to Kailas, the abode of Shiva, in the North. "Why don't you come with me to my city? he once asked Shiva. "Why don't you take me with you?" said Shiva. "I will", said Ravana, his eyes gleaming. "Good", said Shiva, who shut his eyes, and continued meditating.
Ravana then used his massive strength to uproot Mount Kailas with the intention of carrying it to Lanka. "What is he doing" screamed Shakti, Shiva's consort, as the mountain shook, terrifying all its residents. "Have you asked him to do this?" she angrily asked her husband.
Shiva opened his eyes and looked down. "As usual, he misunderstood", said Shiva, pushing down his big toe on the floor. Such was the pressure that Shiva generated, that Ravana buckled under the pressure and found himself trapped under Kailasa's weight. He sang songs in praise of Shiva until Shiva eased the weight, enabling Ravana to slip out. Ravana then went back to Lanka sheepishly.
As he left, Shiva spoke to Shakti, who was looking at him impatiently for an explanation, "I told him he could take me with him. I meant he could understand and internalise the idea that is Shiva and take me wherever he went, for I would be embedded in his soul. He, however, understood it as possessing Shiva. That is why he is very knowledgeable, but not very wise".
