Abhaya Sutta

"And who is the person who, subject to death, is not afraid or in terror of death?
"There is the case of the person who has abandoned passion, desire, fondness, thirst, fever, and craving for sensuality. Then he comes down with a serious disease. As he comes down with a serious disease, the thought does not occur to him, 'O, those beloved sensual pleasures will be taken from me, and I will be taken from them!' He does not grieve, is not tormented; does not weep, beat his breast, or grow delirious. This is a person who, subject to death, is not afraid or in terror of death.
"Furthermore, there is the case of the person who has abandoned passion, desire, fondness, thirst, fever, and craving for the body. Then he comes down with a serious disease. As he comes down with a serious disease, the thought does not occur to him, 'O, my beloved body will be taken from me, and I will be taken from my body!' He does not grieve, is not tormented; does not weep, beat his breast, or grow delirious. This, too, is a person who, subject to death, is not afraid or in terror of death.
"Furthermore, there is the case of the person who has done what is good, has done what is skillful, has given protection to those in fear, and has not done what is evil, savage, or cruel. Then he comes down with a serious disease. As he comes down with a serious disease, the thought occurs to him, 'I have done what is good, have done what is skillful, have given protection to those in fear, and I have not done what is evil, savage, or cruel. To the extent that there is a destination for those who have done what is good, what is skillful, have given protection to those in fear, and have not done what is evil, savage, or cruel, that's where I'm headed after death.' He does not grieve, is not tormented; does not weep, beat his breast, or grow delirious. This, too, is a person who, subject to death, is not afraid or in terror of death.
"Furthermore, there is the case of the person who has no doubt or perplexity, who has arrived at certainty with regard to the True Dhamma. Then he comes down with a serious disease. As he comes down with a serious disease, the thought occurs to him, 'I have no doubt or perplexity. I have arrived at certainty with regard to the True Dhamma.' He does not grieve, is not tormented; does not weep, beat his breast, or grow delirious. This, too, is a person who, subject to death, is not afraid or in terror of death.
"These, brahman, are four people who, subject to death, are not afraid or in terror of death."

Buddha

The Treasure must not be disturbed,

It is not necessary to become totally preoccupied
with worldly affairs. We should take things
easily, and not get caught up in bondage to them,
lest in becoming disturbed we might distress
something greater. The Treasure must not be disturbed,
for if this world should worry, That Other
will transform it, but if That Other is vexed (may
we seek refuge with God!) then who will transform
That?


RUMI

Now it came to pass, as they went, that he entered into a certain village: and a certain woman named Martha received him into her house.
And she had a sister called Mary, which also sat at Jesus' feet, and heard his word.

But Martha was cumbered about much serving, and came to him, and said, Lord, dost thou not care that my sister hath left me to serve alone? bid her therefore that she help me.
And Jesus answered and said unto her, Martha, Martha, thou art careful and troubled about many things:
But one thing is needful: and Mary hath chosen that good part, which shall not be taken away from her.
