Ephemeral

A good way to rise above the fear of falling is to actually become comfortable with going through the act of physical falling in a regular basis in a way that you know you would not hurt yourself in falling.

Being is time and time is finite - it comes to an end with our death. 

Therefore, if we want to understand what it means to be an authentic human being, then it is essential that we constantly project our lives onto the horizon of our death -  what Martin Heidegger called "being-towards-death".

The self can only become what it truly is through the confrontation with death, by making a meaning out of our finiteness.

If our being is finite, then what it means to be human consists in grasping this finitude, in "becoming who one is".

We can then find it possible to grasp the paradox of living in relationship with other humans while facing the fact that one has to be ultimately alone with oneself

Dasein, one's individuality, one's own limited life-span, one's own being.

Heidegger intended the concept of Dasein to provide a stepping stone in the questioning of what it means to be – to have one's own being, one's own death, one's own truth

Da sein (Heidegger)

Lit: There. Being

Or more simply: Being - There

That which "you", in and of oneself without external reference or projection onto or into any other extrinsic signifiers such as language, everyday curiosity or common beliefs.

One's primal nature begins with self-awareness and ends with the snuffing out of self-awareness.

Not to be confused with mindfulness which is a state of being greatly preoccupied with a supra-awareness and reabsorption into externality.

The leap of faith into pure existence requires transcending the world of things. 

Even going beyond ultimate value systems such as

Datta, Dayadhvam, and Damyata,

giving, compassion, and self-control.

Trust that the world and one's very existence will not terminate at any point beyond the material.

Transcendence and immateriality are essential to the sense of truly being there.

This is the looked for end point in koan and other transcendental mindsets.

The ultimate goal of meditation is  the grasp of TS Eliot's  -

"the meaning and approach to the meaning, restores the experience in a 

form".

Existential anxiety is the tendency for the mind to lose sight of pure existence- to be interrupted in the ongoing process of "being there" - of being preoccupied with the thought of existence and the snuffing out of existence through fear of non-existence.
