思虑过多会引发瞋心吗？为什么？有经论可证吗？

思虑本身是建立在我执的基础上的

六祖法宝坛经 楞严经 维摩经 等诸多经典

有论述

这里的思虑 并非忧虑

忧虑只是思虑的一种

凡用思维 皆可称为思虑

(新约)
太(Mat)
6:27 你们那一个能用思虑，使寿数多加一刻呢。（或作使身量多加一肘呢）
Which of you by taking thought can add one cubit unto his stature?

(新约)
太(Mat)
10:19 你们被交的时候，不要思虑怎样说话或说什么话。到那时候，必赐给你们当说的话。
But when they deliver you up, take no thought how or what ye shall speak: for it shall be given you in that same hour what ye shall speak.

(新约)
太(Mat)
13:22 撒在荆棘里的，就是人听了道，后来有世上的思虑，钱财的迷惑，把道挤住了，不能结实。
He also that received seed among the thorns is he that heareth the word; and the care of this world, and the deceitfulness of riches, choke the word, and he becometh unfruitful.

(新约)
可(Mak)
4:19 后来有世上的思虑，钱财的迷惑，和别样的私欲，进来把道挤住了，就不能结实。
And the cares of this world, and the deceitfulness of riches, and the lusts of other things entering in, choke the word, and it becometh unfruitful.
