The Vedas declare that Brahman is of the nature of supreme Bliss (ananda Swarupa). (Sutra Vahini, p. 56)
The best preventive of ill-health is the Amanda that comes of unconcern. Look at Me. I have come with this body and you can see that there is no difference between this body and any other human body. But, yet, illness has never affected this body. It cannot, at any time; even if welcome, it cannot approach me. Nor am I taking any precaution against it. I take all kinds of foods, at all kinds of places, in all types of homes. The dhobi’s room will be full of varied clothes, is it not? My dining table has an equally varied assortment of dishes brought by devotees at the nilyam belonging to all corners of the world. I have no fixed menu at all; I do not care for one. I move about in all varieties of weather; sun or winter, valley or plateau, I drink water from one well today, another well tomorrow. But I am the Ananda Swarupa all the time and so, I am never ill. Nor am I least disturbed by the praise and maligning, that people pour. When I am spoken of either in derision or in adoration, My ananda is the same. A wayside tree having a load of fruits with sweet juice is admired by some, but most people are tempted to throw stones. Even lunatics and senile old men will cast stones at it. The tree will only be happy that it is receiving the penalties for its bounty and contributing to happiness of the hungry and thirsty. (NN S G 30, pp. 13-14)
