need not the physician, but they that be sick" — is an axiom, whoever may have spoken it.
And now, let me bid you farewell for the present until the next. Indulge not in apprehensions of what evil might happen if things should not go as your worldly wisdom thinks they ought; doubt not, for this complexion of doubt unnerves and pushes back one's progress. To have cheerful confidence and hope is quite another thing from giving way to the fool's blind optimism: the wise man never fights misfortune in advance. A cloud does lower over your path — it gathers about the hill of Jakko. He whom you made your confidant — I advised you to become but his co-worker, not to divulge things to him that you should have kept locked within your bosom — is under a baneful influence, and may become your enemy. You do right to try to rescue him from it, for it bodes ill to him, to you and to the Society.
The hill of Jakko is a favourite ride at Simla, whose misty slopes are mentioned in many of the Indian stories.
