Reddit mentions of GATELESS BARRIER PA

My advice:

Don’t ask for a definition in this forum, before you’ve got familiar with the literature from some actual scholars.

1. [Blue Cliff Record] (https://www.amazon.com/Blue-Cliff-Record-Thomas-Cleary/dp/159030232X/ref=sr_1_1?ie=UTF8&qid=1479373811&sr=8-1&keywords=blue+cliff+record)
by the Cleary brothers.

The preface will provide you a good introduction to the history of zen. Plus, insights into the lineage of the masters.

This book is actually a collection of koans. But my advice is: Don't jump into cold water. Makes yourself familiar with the background first (preface's).

2. [Zen Essence] (https://www.amazon.com/Zen-Essence-Shambhala-Dragon-Editions/dp/1570625883/ref=sr_1_1?ie=UTF8&qid=1479374319&sr=8-1&keywords=zen+essence+thomas+cleary) by Thomas Cleary.

Cleary provides quotes/ sayings from the masters referring to “topics” or “questions”, like “Zen Teaching?”, “Basis of Zen?”, “Summary of Zen Practice?”.

I think this approach is very helpful for people who want to get introduced to Zen, in terms of “What the hell is this shit about?” -- good guy Thomas Cleary!

3. Gateless Gate
by Robert Aiken.

This is rather a workbook for the practitioner than literature regarding zen.

I haven’t read the book I’ve linked to, but in my opinion, starting with the Mumonkan without any notes or comments from contemporary scholars/ students/ teachers/ translators is not the right approach. Use the commentaries from Aitken only as an orientation or a hint. The meaning itself has to be found by you!

So you would say that Zen Mind Beginners Mind offers only a "superficial understanding" of Zen? Interesting, not something I had heard before about that book.

If I were to order one of those books off your list to start with, which one would it be?

And is this the Mummonkan book you mentioned?
