Nobody can ever pull us out of samsara, our liberation and enlightenment depends on ourselves alone. But until we have the very deepest understanding of what we have to do, we need to take refuge in the Buddha, the Dharma, and the Sangha - the unsurpassable teachings and teachers who clearly indicate the direction that we have to go in.
Ultimately, however, we are our own master. When we know exactly what we have to adopt and what to reject, without any misunderstanding whatsoever, we'll no longer need that direction. But until that time comes, refuge is a vital part of our path.
The attitude and intention for embracing any Dharma needs to be a real and deep-rooted one, not an emotional one. Many people with fleeting emotions think that they have the required mindset, but they haven't, and they also have immediate expectations for some great results.
But if you practise Dharma with such an idea of worldly reward or achievement, then that is not the real practise of Dharma. Practising Dharma needs a long-term determination to practise continuously in this and all the coming lifetimes.
So I think that has not matured in the minds of many new Western Buddhist practitioners, and due to this short-term expectation and day-by-day evaluation, which hardly shows swift progress, one day you will find yourself frustrated and give up the practise.
So before entering into the practise, you must have a deep understanding and study, and then examine yourself, whether you are able to endure it on a sustainable basis and only then should you get into the practise of Dharma. Otherwise it will become a kind of child's play and that may be no good for anyone.
