First we must come to an agreement what confidence means.
What does it mean to you?
Sanguine is more a form of trust in yourself, a knowing that all will be well, that everything will be fine.
Trust in yourself and the outcome.
Ascension is more of a strength and power, you feel this power in yourself and with it comes a knowing that you will be able to handle everything on your path.
The Ascension one is more fiery and volatile, where as the one from Sanguine is more airy — meaning that with Ascension your confidence will express in actions more so than with Sanguine which is more like “laughing” the problems away, being very good at talking your way out of things.
Essentially with Sanguine you are confident in your speech, your talking, and with it you can turn negative mentality in positive mentality.
If someone tells you on Ascension you can’t do something, you, with your power will show him or her that you can. Less talk more action.
Hopefully this helps.
It’s all forms of confidence but how it expressed is different.
If you have some knowledge of the universal elements you will understand it better because each element has a different expression and confidence can manifest through all of them.
These elements are primordial and from them everything in existence is forged.
