Definition - What does Aham Vimarsha mean?
Aham vimarsha is a Sanskrit term referring to a perfect self-consciousness or a perfect sense of “I am-ness.” Aham translates to "I am" and vimarsha means “free will” or “will-consciousness.” It can also be defined as the “spontaneous vibration of self-consciousness.”
Yogic philosophy explains that the experience of aham vimarsha encompasses simultaneously experiencing one’s own absolute freedom, infinite bliss (or ananda) and the glory of being. This is described in the scriptures in references to Shiva’s recognition, through his inherent shakti, of his own self-consciousness. Thus, aham vimarsha can be considered the essential nature of Shiva and, consequently, the absolute Self.
Yogapedia explains Aham Vimarsha
Aham vimarsha is an important concept in yogic philosophy because it confirms the yogi's goal of achieving liberation, or moksha. When a yogi reaches the realm of liberation, they also realize their own perfection and embrace their true nature.Some yogic teachings describe the vibration of aham vimarsha as being the vibration through which shakti exploded and manifest itself into the infinite number of forms and shapes that exist in the universe. Thus, aham vimarsha is an instigating and fundamental step in the yogic philosophy of creation.
