Heart
The heart is the feeling capacity of the soul, the soul’s
capacity to know intimately. (Spacecruiser Inquiry, pg 144)

Heart and Truth
The heart’s love of truth is not a thought or an idea.
It is not a matter of trying to live according to an ideal. It’s
not a motive that comes from the mind. It is an impulse from the
depth of the soul, a deeply felt motive from the heart. It is
not that we think and deliberate and decide that truth is good
for us, so we end up wanting it. Love of the truth is not utilitarian.
The truth often ends up being utilitarian, but that is not what
inspires the right attitude for the journey. The correct attitude
is that of a lover who wants to be close to the Beloved. (Spacecruiser
Inquiry, pg 126)

When you really like to discover the truth, when you just like
to see and feel what’s true, this indicates that you like
being yourself. It is lovely to be where one is without rejection,
without the need to be somewhere else to be okay. In this place,
the heart opens up, and there is enough space to feel joy. There’s
contentment and peacefulness, and a personalness to the contentment
and peace that gives the feeling of intimacy. You are intimate
with yourself when you’re simply being where you are. (Spacecruiser
Inquiry, pg 196)

Courageous Heart
The courageous heart is independent of what the other person
does and what the other person thinks of you. To have a courageous
heart, you need to accept a certain kind of aloneness, a certain
kind of independence. With the courageous heart, you are so independent
that the person can do all kinds of unpleasant things but you
can still see the reality. In that independence, the feeling is
that you have to give constantly, regardless of what the other
person does or what the situation is. (Diamond Heart Book 4, pg
203)
