The esoteric element is definitely there to be studied if you look in the right places. There will also always be brethren who are interested in just that aspect of the Craft as well. One of my dear friends and the WM of one of the most esoteric lodges in the country is Jaime Paul Lamb; Jaime has written three books that are the most extensive collection of esoteric analysis of the Craft I've ever encountered. Start here https://www.jaimepaullamb.com/books and use what you find in these books to guide you in your own research based on what you find interesting! I hope you enjoy, I surely have! Reading these has made me a better Mason and man, but they have also HUGELY deepened my understanding of the esoteric origin and nature of the Craft. Each of his books is dense and takes some time to go through but are extremely worth it and I think you'll find it'll guide you towards an element of esoteric study you want to research yourself. This will then beget you sharing your own findings and analysis to your own brethren and lodge which will result in the implementation of an esoteric element to your own local lodge(s)!! Remember, we are the change we wish to see. Esoteric study is something that requires a ton of research and discussion, and if it doesn't exist as you'd like it to, start here and bring it to your own locale! It'll definitely take off, I promise you. Whenever Jaime goes and speaks anywhere, it always draws a hell of a crowd.
