“Those observations are but foul,
Which make me wise to lose my soul.”
"Childhood".
Silex Scintillans (1655)
Context: Why should I not love childhood still?
Why, if I see a rock or shelf,
Shall I from thence cast down myself?
Or by complying with the world,
From the same precipice be hurled?
Those observations are but foul,
Which make me wise to lose my soul. And yet the practice worldlings call
Business, and weighty action all,
Checking the poor child for his play,
But gravely cast themselves away.

Pragmatism and Pragmaticism (1903)

Context: Others have provided maps for the psyche, but I've never trusted them. Those maps carried the marks of too many name-places in this reality. When you travel through the psyche, you necessarily journey through your own deepest mind -- and as you travel into inner realities, this means that you move into another kind of atmosphere, as you would if you were travelling in outer space. In the past, others have projected phantoms of their own minds there, then acted as if these were natural signposts. In my journeys I refused to follow those paths, feeling that they were not safe or dependable and fearing that they might cloud my own view or make me lose my way.

“And into the forest I go, to lose my mind and find my soul.”
Once again, this is far from Muir's style of writing. The quote does not come up in any search of John Muir's Journals or his published texts on the John Muir Exhibit website. It is most commonly put on t-shirts - never in any scholarly source.

“My observations are those of a beginner.”
Mount Analogue (1952)
Context: My observations are those of a beginner. As they are completely fresh in my mind and concern the first difficulties a beginner encounters, they may be more useful to beginners making their first ascents than treatises written by professionals. These are no doubt more methodical and complete, but are intelligible only after a little preliminary experience. The entire aim of these notes is to help the beginner acquire this preliminary experience a little faster.

Essay as "Mr. X" (1969)
Context: There's a part of me making, creating the perceptions which in everyday life would be bizarre; there's another part of me which is a kind of observer. About half of the pleasure comes from the observer-part appreciating the work of the creator-part. I smile, or sometimes even laugh out loud at the pictures on the insides of my eyelids. In this sense, I suppose cannabis is psychotomimetic, but I find none of the panic or terror that accompanies some psychoses. Possibly this is because I know it's my own trip, and that I can come down rapidly any time I want to.
