I've spent some time in monasteries in the Ajarn Chah tradition of Thai Buddhism. The most common form of meditation is observing the breath at the nose. Importantly in Buddhism, when observing the breath, don't control the breath but rather observe how it wants to be. Inevitably, the mind will wonder from the breath. It's important to kindly and gently come back to awareness of the breath. There are other forms of meditation as well, but this one and it's variants is probably most common. Very mercifully, I've never had visions in meditation. But recently I've been feeling a lot of weirdly physical pleasure in my head and shoulders from the samadhi--concentration or calmness--that comes from my practice. I've also had more "insight," which just means I notice more internally and externally. In Buddhism, we talk about how concentration and insight are the goals and results of meditation. It's important when talking about meditation, however, to mention sila, or morality. Sila for a common person means following the five precepts--not to kill any living creature, not to steal, not to commit sexual misconduct (rape, adultery, etc.), not to lie, and not to take intoxicants like alcohol and cannabis (caffeine is okay). Many teachers often say that if you summarize Buddhist practice, it's just sila, samadhi, and pañña, which means morality, concentration, and wisdom. If you want results from your meditation, also practicing the five precepts is a good idea. I suppose the final result for me is that after studying Buddhism in college more than ten years ago and then spending several years in Thailand in my 20's, I'm taking steps now to seek ordination as a Buddhist monk. I'm in the very early stages of turning my life upside down, but those are my results right now. So if you don't want to give up your worldly possessions and pick up the robe and bowl, don't meditate. Lol. I kid.
