There are many sources, I don't even remember all. Some significant that influenced me:
I used to be quite anxious so somehow I started to read about anxiety in psychology book, that was around age 11 or so. Later on in teens I started to read S. Freud. Did pretty good part of his work but it never matched what I was looking for. I think Freud is good overall, though (IMO) things like Ego or ID are just not intuitive enough, there is simply much more underneath...
Then I found a book about Mahayana Buddhism, Mysticism, different yogas (Radja, Bhakti,..) and so on. I think I was like 15 or so, the author published perhaps 20+ books about these topics. That was quite shocking discovery, it totally transformed my life. In essence, it was a study and practical knowledge of 'self': consciousness, awareness, attachment, morals, suffering....
Those books gave me what I was looking for at that time, till today I still think they are deeper than psychology. At that time I was practicing martial arts, so both of these were my life, one physically and the other mentally, both hand in hand. I was quite close to make it all my life, trained briefly with e.g. Okinawa masters. I just lived it and loved it, hard physical exercises, fighting, some weights lifting to it, meditations, study of Buddhism, some yoga.... At that time I was shy and clueless about girls, but only years later I realized that all of these gave me excellent fundamentals as a side effect...
Anyway, the point is that I just didn't read a lot, I practiced a lot as well. If these things interests you, you would probably benefit from Mahayana Buddhism and/or yoga studies, and mainly practice. The sources I mentioned were in different than English language, but reasonably similar style and topics would be books from Swami Vivekananda.
... I didn't feel like a true fighter though, I had some reserves about making it as a life style, so I let it go. Then I somehow ended up in USA with a great desire to make $$$ and achieve formal education. Part of the education was also heavy psychology, and although I don't particularly enjoy much psychology I probably gained decent understanding over the years.
I read some motivational books and listened to audios, Tony Robbins is great. A must read.
I also read lots of stuff from Osho, it was just a continuation of previous knowledge about Buddhism. Osho answered all the questions I had unanswered or things I didn't fully understand in Buddhism, that was just "it". Osho is very weird though. I read the books and they were great, lots of wisdom. Then I saw him on YouTube, and there is just something unnatural about him, I was sort of disappointed I him as a person. Simply weird, no vibes, no congruence... But definitely the wisest books I've ever read...
As far as spirituality, another great book is Bhagavad Gita, which in essence is Bhakti yoga... When you understand and practice, you may find that you e.g. Understand Jesus much more. Some could even claim that Jesus was in essence practicing Buddhism, this kind of yoga, but again - nobody wants to have religious war just because there are great similarities....
As far as seduction, there are great authors such as Ross Jeffries, DeAngelo, Brodski, 60 years of challenge... I don't even remember the rest anymore. If this was seduction 1.0, Chase definitely took it to 2.0, totally new level, great work. But you always want to see other authors as well to broaden your knowledge, see the same thing from different perspective. It all just gives you another knowledge of e.g. Females, but also of self...
I was also amazed with NLP and hypnosis for a short time, tried to read Bundler and Erickson but it was just so dry for me that I gave it up after a couple of pages. Never got into it deeper, definitely a great stuff but at the same time it is just too much "psycho" for a guy... IMO one hour of weight lifting is more beneficial to a guy than one hour studying NLP, but that's just my opinion...
There is a book that Ray keeps recommending here on GC: "Healing the shame that binds you" That's a great work, definitely one of those 'must read', lots of female psychology, lots of understanding of self... Simply a must...
So there are many different aspects of person's life than one should focus on. A younger guy should focus on exploring different areas of his life, getting education, practicing fitness and/or martial arts, leading healthy lifestyle, learning about motivation and making sure that he can make enough money to live comfortably, practicing spirituality, going out making friends, working on social skills/being friendly, expanding horizons by talking to different people...
Lots of things in life to do, many things to see and understand, lots of great things to achieve... All these enrich the person's life, all these contribute directly or indirectly to seduction anyway. A guy who "fixes" these things, who "fixes" his life will eventually find that there are plenty of amazing women interested in him, simply because he has a great life to live - thus they want to join and have great life as well....
And that's the true secret, doing these things should take 90% of guy's effort. The guy should be so busy that he doesn't even have a time for girls, maybe just 1-2 days per week he can spend some time on girls. The rest 10% is only seduction, fine and tuned skills to have fun with women... The secret is not to read only about Buddhism or martial art, the secret is to DO it. The secret of seduction is not to read about it, but DO it. Unfortunately many guys have it backwards, they study seduction 90%, they spent 6 days out of 7 on seduction - while ignoring important things in their lives...
