Formal sitting practice is the most direct and simple way to gain real insights into the nature of reality and become enlightened.
There are two main types of meditation that are benifitial in this regard.
The first is training in concentration. You sit attempting to focus your attention on a single meditation object for as long as you can. Over time, your ability to focus will increase, and that will assist you in your second type of meditation.
The second is training in insight/wisdom. For this practice, you use your ability to concentrate to sit and observe a specific aspect of your experience in an attempt to see it for what it truly is.
Through gaining insights into the nature of reality and who you really are, you will gain benefits such as compassion, mindfulness, peace, happiness, disillusionment, and true knowledge. These ultimate understandings, once known clearly in your own experience, brings about the meaningful benefits of Buddhist teachings.
Enlightenment is possible for everyone this lifetime. I wish you nothing but love and hope you find what you are looking for. 🙏
