Hello Rhys,
I want to encourage you to learn the pure Dhamma as presented here on the website. When you reach a certain level of knowledge and understanding you will start feeling niramisa sukha, the cooling down. As you proceed on the path dhamma will guide you and there is no way back. One feels the validity of the Dhamma and pieces fall into place. If one works diligently with an open mind, the stream entry is guaranteed.
