The "impulse of life" can be described in various synonymous phrases such as "instinct for survival," "urge for existence," or "drive for living." It is the powerful force within all living beings that motivates them to seek out nourishment, reproduce, and protect themselves from harm. Other synonyms that capture this life force include "vitality," "energy," "vigor," and "animation." Without this impulse, organisms would lack the will to carry out necessary actions and ultimately cease to survive.
