Can you think of anything more real, more tangible, more solid than the taste of food you are putting into your mouth, as you chew it, as it touches your tongue? Breakfast bacon - the taste, the texture, the aroma. The entire experience of eating bacon for breakfast. When you are eating it, is there anything elusive about the bacon you are eating?
Not likely.
But if you didn’t have bacon for breakfast and, instead, decided to learn about having bacon for breakfast, to study it, to listen to lectures about bacon, to watch videos of people eating bacon, to read books and blog posts and answers on quora about how it feels to eat bacon, and what it means, and how it tastes, and whether it is right or wrong to eat it - if you did all that studying and searching and learning, how real, how tangible would the experience of eating bacon be to you?
Not very, I’d imagine.
The spiritual truth is so elusive because you are not biting it, you are not chewing it, you are not swallowing it. Yourself. Directly.
You are searching for the taste of the truth in descriptions given you by others of how their truth tastes. Instead of eating your own.
