A disciple once approached his Guru and said that he did not find any progress despite devoting his time to meditation.
The Guru pointed out that he had not been really practising enough. He also alerted that death was immanent in about a week (for the disciple) and if he did not practise properly, self realisation would be postponed for several births.
The disciple on realising the seriousness of the issue, devoted his entire time for meditation. At the end of seven days, an impenetrable calmness had descended on him. When he met the Guru, the Guru pointed out that in his earlier efforts there was a lack of diligence and dedication. Hence he had to lie to him that he was to die in a week simply to push him to practise more. He also pointed out that only dedicated efforts can bring about self realisation.
The Hindu story thus conveys the truth of diligent efforts.
