However you know that some of those folks teaching are not aligned with Islam in principle.
Ponder then what is islam? for me it's not a label or name of a religion.
Yes what Jesus teaches, Siddhartha teaches, Lao Tse teaches is not aligned with the religion labelled Islam, Catholicism, Prostestanism, Orthodoxism, Rabbanical Judaism. In fact they're at the opposition.
The difference between islam and religion named Islam is like the difference between democratic and democrat party. One is a characteristic the other one is a political party. You can find democrats not only within democrat party, infact many members of the democrat party are actually not democratic at all.
“Not my will, but yours be done,”
-- Jesus, Luke 22
"Only three things matters: how much you loved, how gently you lived, and how gracefully you let go of things not meant for you. As the root of all suffering is attachment."
-- Siddhartha
For example: As per Buddhism the concept is we are trapped souls that are used by a higher civilization. and we are controlled by the mechanism of karma and the wheel of samsara- a continuous life-death cycle -
Yes the law of action (also known as Karma) is a universal law, expressed by many statement such as it's the 'what goes around comes around', 'whatever good things that you do you are doing it to your own soul, whatever bad things that you do you are doing it to your own soul', 'forgive and you shall be forgiven, judge and you shall be judged'.. etc..
Life ends with death and death mark the beginning of 'life', the end always mark the beginning of something else and the beginning marks the end of something else, it's two side of the same coin. It's the universal law of anything. The end of Nazi Germany marks the beginning of Democratic Germany, the end of a star marks the beginning of new star (or even stars).
Soul is not 'trapped', it's the consciousness that is 'trapped', if we want to use that word.
Trapped to it's own attachment towards something, so nobody trapped it, it's trapped by it's own attachment.
As such that 'letting go' shall break those attachment.
And 'forgiveness' is among the expression of 'letting go', thus many say 'forgiveness shall break the bond of karma'.
"Forgive others not because they deserve forgiveness, but because you deserve peace"
-- Siddhartha
"forgive us our debts, as we also have forgiven our debtors."
-- Jesus
Or better yet not to get into the attachment situation in the first place.
"I cannot forgive you because I have no grudge against you."
-- Siddhartha
Now if the above is true then it is not aligned with Quran . so how do you mix and quote Quran along with such other quotes?
I only accept those which resonate with my conscience, regardless of the sources.
That's what Jesus did when he read the Torah by the way... some of the passage there troubled him, thus he start the journey of seeking, following his conscience. The same goes with Siddhartha, Muhammad, Rumi and many others, their 'journey' usually start with something that troubled them. Troubled their conscience.
Conscience, everyone has it and it's the ultimate guide.
Although known by many names, some named it as "Holy Spirit" (Ruhul Kudus, Ruach Ha Kodesh), some named it Atman (The ultimate self) and some others call it as "Higher Self".
Nonetheless everyone has it without exception, including you.
