The greatest of these lessons is the crucial yet under-appreciated art of letting go. That means, first and foremost, letting go of expectations. Indians know a thing or two about this. In the Bagavad Gita, a Hindu holy text, Lord Krishna says to Arjun, in effect: Give 100% effort to the task at hand but have precisely 0% invested in the outcome. This is, of course, extremely difficult to pull off. Normally, the more effort we exert, the higher our expectations – and, often, the greater our disappointment. Krishna’s advice, I think, is one that travellers to India would be wise to heed. Arrive not with high expectations, or low ones, but with no expectations. Let go of expecting anything.
