Here are the quotes:

.......................................................

Ramana Maharshi

"The fates of all souls are ordained by God in accordance with their past deeds; whatever is destined not to happen, will never happen however hard one may try. What has to happen will happen, do what you may to prevent it. This is certain. The best course, therefore, is for one to abide in silence."

........................................................

Adyashanti 

“We’re not bringing struggle to an end. We’re not trying to not struggle anymore. We’re just noticing that there is a whole other dimension to consciousness that, in this very moment, isn’t struggling, isn’t resentful, isn’t trying to get somewhere. You can literally feel it. You can’t think your way to not struggling. There isn’t a three-point plan of how not to struggle. It’s really a one-point plan: Notice that the peace, this end of struggling, is actually already present."

Eckhart Tolle

"Action arising out of suffering is contaminated with suffering and causes further suffering, and that is karma. Action that arises out of a state of "acceptance" is totally free of karma. And there is a vast difference."

"The mental suffering you create is always some form of non-acceptance, some form of unconscious resistance to what is. On the level of thought, the resistance is some form of judgement. The intensity of the suffering depends on the degree of resistance to the present moment."
