Truth is the One which is immovable, Unshakeable, Constant and unchanged which transcends all times/dimensions of perception.
The term is most often related to God/Almighty. Truth in Spiritual terms can be explained in the following 3 forms:
This virtue can be used to realize the mistakes in us and move forward in our journey… To accept the past and move forward.
Awareness of this virtue leads us into light/hope/courage from ignorance/fear/darkness… e.g., Listening to inspiring conversation/Being in an intense moment of meditation makes us realize and move on from our present time.
A quote/mantra from one of the ancient Vedic scriptures about Truth:
“Aum Asato mā sad gamaya
Tamaso mā jyotir gamaya
Mṛtyormā amṛtam gamaya
Aum śānti śānti śānti”
meaning of which is –
“From ignorance, lead me to truth;
From darkness, lead me to light;
From death, lead me to immortality
I’m peace, peace, peace”
