There are several paths to awakening, but what all paths have in common is that they surpass the mind. This is why meditation is a helpful tool. Meditation as most people know it is a tool one may use to help 1) control or quite to mind and 2) surpass the mind.
The most direct path is to go directly through mind without using any "outside" tools such as anything that feeds the senses.
Nisargadatta taught to focus all your attention on "I am" sit with it and keep affirming it. Ramana Maharsi taught to ask the question "Who am I?" This is considered "Self - inquiry".
I was seeking the Truth, not enlightenment, awakening or my Self. I wanted to know the Truth. My meditation was "Truth - inquiry" and my question was: "What is the Truth?"
When we sit with nothing but ourselves in meditation and focus our attention on a question such as :"What is the Truth?" the mind will answer that question. When we repeat that question we will continue to receive answers from the mind. These answers are all based on information we have gathered throughout our life, either from others or from our own conclusions.
When the mind has reached the end of all this information it "gives up" and the real Self/Truth is revealed.
Enlightenment is not something we "get" it is something we already are and realize once the veil of ignorance is lifted.
