A component of rasadhvani.
anubhāva  "sign or indication of a feeling by look or gesture, dignity, authority, consequence" (36)[1]
In Physics
Based on rigidbody Newtonian physics.
resultant  "A vector quantity that has the same effect as two or more other vector quantities of the same kind" (510) [2].
vector  "A quantity in which both the magnitude and the direction must be stated. Force velocity, and field strength are examples of vector quantities. Note that distance and speed are scalar quantities, whereas displacement and velocity are vector quantities…" (623) [2].
Resultants can also equal ZERO, such as when two vectors with the same magnitude push at 180° (directly headon).
A more complex ZERO Resultant with three vectors is shown below in the third example.
Parallelogram of vectors
"A method of determining the resultant of two vector quantities. The two vector quantities are represented by two adjacent sides of a parallelogram and the resultant is then the diagonal through their point of intersection. The magnitude and direction of the resultant is found by scale drawing or by trigonometry" (415) [2]. 
Finding the resultant graphically through scale drawing
When graphically adding the vectors, only their position (the x , y coordinates of the start and the end) is shifted.
In mathematical terms, the vectors are translated.
Direction (in degrees, eg. 45°) and magnitude of the second vector is maintained.
The two vectors pull on the same point. The two are added together to create a parallelogram (See above).
This line has direction (moving away from 0 , 0), and magnitude, making it another vector. This is called the Resultant vector. 

Two vectors push on a point. The three are added together. The direction (in °) and magnitude are maintained.
The Resultant summarizes a, b and c into a single vector. 
ZERO Resultant
Two vectors, a = (0 , –y) and b = (–x , 0), push on a point. (0 , –y) + (–x , 0) + (x , y) = (0 , 0) The (Resulant), R, equals ZERO. 
A Resultant of 0 means the object remains at rest and is in “stasis”. The cancelling forces create an equilibrium, where forces are balanced, rather than no forces acting.
In Rasadhvani
The components of dhvani interact. The character (āśraya) can exert will, agency, tapas, etc. The "vectors" of the different bhāvas are added. This creates some resultant on the part of the character (action, inaction, thoughts, etc). 
Book of Mormon
Sons of Mosiah (Alma 17:312)
But this is not all: they had given themselves to much prayer, and fasting, therefore they had the spirit of prophecy, and the spirit of revelation…Now these are the circumstances which attended them in their journeyings, for they had many afflictions; they did suffer much, both in body and in mind; such as hunger, thirst and fatigue, and also much labor in the spirit.
