般若波羅蜜多心經 Mantra : 無智亦無得 以無所得故 No wisdom and no Gain because Nothing can be Gain

無智亦無得, 以無所得故

Let's look at some Principles behind this text (and I don't even agree with my interpretation of things here);

無"智"亦無"得", 以無所得故
"智" is said to mean the "Great knowledge or Great Wisdom" which is "大智慧" and that's the entirety of the "般若波罗蜜多心经" in one single Word. And that the next word of "得" would mean the attainment of the final voyage of life; that is Nirvana "功德圆满" or "湼槃". If one reads the first part literally 無"智"亦無"得"; it sounds like if that "If one does not Realize the "Great Knowledge" and therefore one will not get to achieve the intended Journey". 
But "無智" is a funny thing, it is in the essence of one's realization that one is not filled with knowledge (or in this case, will one really know if the right knowledge was attained!). And that is ridiculous to indeed say that one will ever really realize the attainment of such "Divine knowledge" because if that's true; of the words of the MANTRA, then one at that point would have been at the verge of the state of Nirvana. And don't forget that the beginning of the Mantra keeps on mentioning that "色即是空, 空即是色", in that ALL things are EMPTY anyway; and at that State of Mind, ONE attain that "EMPTYness" or "NOTHINGness" where "無眼耳鼻舌身意, 無色聲香味觸法". 
"無智" is so important here in the principles within MANTRA in that it is the state of mind of one knowing that one is "Without Knowledge" or "Without Wisdom", that one pursues that "True Knowledge of Wisdom" and ironically when finally one finally presumably really attained that "Great Wisdom", at the state of Nirvana that "Knowledge suddenly becomes  NO MEANING" anymore because that final state of mind is "空" EMPTY. The True Freedom from the "Pain and Sufferings of Re-Birth" STOPS when there isn't any more cycle of Re-Birth when the state of mind is "空" EMPTY.
So, I ask myself, why bother! as nothing is REAL in this world if we truthfully believe about the Concept of "空" EMPTY. As we live in a world of "有眼耳鼻舌身意, 有色聲香味觸法"; because we hold consciousness in this world by our Eyes, Ears, Nose, Tongue, Body, and Mind in the physical body using them to learn and yearn relentless for the Colors, Sounds, Smells, Taste, Touch, and Thoughts in this physical world. The MANTRA urge believers to embrace ""無眼耳鼻舌身意, 無色聲香味觸法" that is to give up the consciousness of all Senses. Hence, Give up all your Senses and that will remove all your Sufferings and Cravings for the worldly things presented through 色聲香味觸法!

As a simple man, let me say something about
無"智"亦無"得", 以無所得故,
to simply mean "If you do not get knowledge then you get nothing, and when you start suffering endlessly; don't start complaining about it"

So, What is knowledge! 
Is it just about that "般若大智慧 Great Wisdom" (something that no one really know what it is, which is only still an IDEA about Life); should everyone then, start that search of the so called "Great Wisdom" and abandoned all other "Knowledge" which has no meaning because there are only worldly things exist in the 颠倒梦想的世界 fiction of our imaginations in the physical world we think we live in! The pursue of "any other knowledge" would create 渴望 more craving in this physical world until the day one seize to exist. 

Scary though! isn't it? 

"無智"亦"無得", 以"無所得"故
As a simple being, I like to take it simple and look at iy this way:
"Pursue the knowledge you desire (what ever it may be) and be very good at it. If you love cooking, go ahead and study the knowledge of cooking, and that you may or will never be the best chef in this world (and it doesn't matter). When you do something in passion and you like what you are doing, it does not matter if you have only one audience or no audience (in many case, you are always your own audience), you have achieve something for your own self and not for someone else. It is when one stops to pursue any knowledge with passion and that is where one really never get anything in this life." 

心經 The Mantra : 以無所得故

《心經》

... 是故空中無色。無受想行識。
無眼耳鼻舌身意。無色身香味觸法。
無眼界。乃至無意識界。
無無明。亦無無明盡。

乃至無老死。亦無老死盡。
無苦集滅道。無智亦無得，以無所得故 ...

这一回是说

《以無所得故》

這一句是總括以上
“是故空中無色，無受想行識……無智亦無得”
那麽多句表示一切法不可以說有所 “得”, 一切法是不可以執取的 (堅持自己的在意)，凡有所執取，就會生起貪嗔癡，贪、嗔、痴为三毒
I think it is ever our "Craving" mind that "Want" something that creates the beginning of all sorts of evil behaviors like Greed, Anger, and Craziness.

贪是贪心、嗔是恼怒、痴是糊涂
Greed, Anger, and Craze are the three poisons.

全都是錯誤的行为 , 例如這個揚聲器，清清楚楚正在播音，有擴大聲音的作用，如果說它是沒有的，就說不通；但如果說它是真實不變的揚聲風，也一定錯。一切都是缘起，是因为我们喜欢听的好听的声响。

世間一切事物，都以不實為性，就比如说有一天你是不喜欢听音乐了, 那么那个揚聲器所发出的音响也没作用了。缘灭了就不在需要揚聲器这个东西了。

所以
一切是無決定性的，一切都是 缘起缘灭，缘聚缘散。
一切都是天意, 一切是隨緣。
Nothing is permanence, all things come and go, what will come will come and what will go will go.

而成、而住、而壞、而空的
Forming, Existent, Decay, then Vanished。

一切事物的形成，存在，坏掉，然后消失
都是天意而无所避免的。

以《無所得的心》，
去行菩薩道
並不是求什麼，

沒有要名，沒有要利、沒有要地位，
Not Fame, Not Prosperity, Not Status。

《什麼都不要》，"To Want Nothing" means the True Buddhahood。
這個才是真正的菩薩
