How can the antimaterial particle be explained? We have experience with material particles or atoms, but we have no experience with antimaterial atoms. However, the Bhagavad-gītā gives the following vivid description of the antimaterial particle:
This antimaterial particle is within the material body. Because of the presence of this antimaterial particle, the material body is progressively changing from childhood to boyhood, from boyhood to youth to old age, after which the antimaterial particle leaves the old, unworkable body and takes up another material body.
This description of a living body confirms the scientific discovery that energy exists in two forms. When one of them, the antimaterial particle, is separated from the material body, the latter becomes useless for all purposes. As such, the antimaterial particle is undoubtedly superior to the material energy.
No one, therefore, should lament for the loss of material energy. All varieties of sense perception in the categories of heat and cold, happiness and distress, are but interactions of material energy which come and go like seasonal changes. The temporary appearance and disappearance of such material interactions confirms that the material body is formed of a material energy inferior to the living force, or jīva energy.
Any intelligent man who is not disturbed by happiness and distress, understanding that they are different material phases resulting from the interactions of the inferior energy, is competent to regain the antimaterial world, where life is eternal, full of permanent knowledge and bliss.
The antimaterial world is mentioned here, and in addition information is given that in the antimaterial world there is no "seasonal" fluctuation. Everything there is permanent, blissful, and full of knowledge. But when we speak of it as a "world," we must remember that it has forms and paraphernalia of various categories beyond our material experiences.
The material body is destructible, and as such it is changeable and temporary. So is the material world. But the antimaterial living force is nondestructible, and therefore it is permanent. Expert scientists have thus distinguished the different qualities of the material and antimaterial particles as temporary and permanent respectively.
The discoverers of the two forms of matter have yet to find out the qualities of antimatter. But a vivid description is already given in the Bhagavad-gītā as follows. The scientist can make further research on the basis of this valuable information.
