This brief and simplified discernment is to elaborate on the following presentation https://www.youtube.com/watch?v=a__OGBWfO-0:
There are 3 types of Truth:
1.0 Relative Truth
And there are many types of relative Truth just as the word means such as:
1.1 Truth that applies to certain things or circumstances and not others.
1.2 Truth that applies to known physical realm and world. And not to realms and worlds beyond the known physical world
1.3 Truth that evolved.
1.4 Truth as aspects of parts rather than sum of parts.
1.5 Truth in relative to the Source of Existence or Truth as sum of parts rather than in the context of the greater whole.
2.0 Absolute Truth.
Can be considered as the Ultimate Truth perceived and experienced at and from the Source of Existence. Both Relative Truth and Absolute Truth can be experienced while in the many sentient composite body-mind system in the known physical world. Perhaps just a glimpse of Absolute Truth. However, Absolute Truth can only be through the real or subtle body-mind while for Relative Truth, it can be both physical and or subtle body depending on the perception and experience realms and worlds (i.e. for example, experiencing the spiritual realms and worlds would require the subtle body-mind while it is not necessary for many experience in the known physical world).
3.0 Universal or Eternal Truth
However, all things are impermanent and evolving or the greater whole also evolves. And if the individual form-formless (and perception and experience) do not exist along, then Universal Truth or Eternal Truth is not possible. In other words, in order to perceive and experience Universal or Eternal Truth one has to achieve Universal or Eternal form-formless. It should be obvious by now to all that biologic or physical body can NEVER be eternal.
And therefore, Truth not only matter but is essential toward meaningful self and collective transformation, empowerment, and liberation (which would include survival) in the known physical world. And beyond such as eternal existence or immortal bliss potential. And which is why metaphors such as "The Truth Will Set Your Free", "Resonate With Truth", "The Truth Will Save You", "Truth Cannot Exist In Absence Of Heart", "Love In Truth", "Truth In Love", "Love Of Wisdom And Truth", "Truth Is In The Essence, Nature, and Ground of Being", "Truth Is In The Essence, Nature, and Ground of Nature", and among others.
And of course metaphors such as "Go Inward", "Seek Within", and "Know Thyself" imply that the Truth can be found within (in the essence, nature, and ground of being. And nature through skillful means such as nurturing, developing, and transforming the many sentient composite body-mind system accordingly). While or even through Truth is adaptive or flexible priorities during daily living and struggle, it is the ultimate inspirations, aspirations, and yearnings of authentic and sincere naturalness-spiritual practitioners and sages throughout the age. And which are more or less or can be said of inspirations, aspirations, and yearnings in the scientific quest.
In brief and simple words, beside main principles of or for quality, well being, purposeful life, meaningful transformation, common and greater, and the betterment of sentient; both disciplines and practices seek meanings and purposes of life and existence in Truth. And which are the reasons naturalness-spiritual practitioners practiced science ((as an example http://www.phayul.com/news/article.aspx?id=41644&article=%e2%80%9cThe+Dalai+Lama+%e2%80%94+Scientist%e2%80%9d+set+for+World+Premiere+at+76th+Venice+International+Film+Festival; http://www.peacejam.org/the-dalai-lama-scientist)) and scientists practiced naturalness or were also nature philosophers. Naturalness and spiritual would be part or acceptable in organized science had not for prohibition over the age or due to forbidden knowledge and practices doctrine.
As an example, without Truth, human species is heading toward de-evolution and potential extinction (https://www.epistemologyontologyfoundationinstitute.org/de-evolution-and-existential-risks.html) in the known physical world. And beyond. And extinct many more other species along the way.
