When the living entity forgets his constitutional position as an eternal servant of Krsna, he is immediately entrapped by the illusory, external energy. The living entity is originally part and parcel of Krsna and is therefore the superior energy of Krsna. He is endowed with inconceivable minute energy that works inconceivably within the body. However, the living entity, forgetting his position, is situated in material energy. The living entity is called the marginal energy because by nature he is spiritual but by forgetfulness he is situated in the material energy. Thus he has the power to live either in the material energy or in the spiritual energy, and for this reason he is called marginal energy. He is sometimes attracted by the external illusory energy when he stays in the marginal position, and this is the beginning of his material life. When he enters the material energy, he is subjected to the threefold time measurement-past, present and future. Past, present and future belong only to the material world; they do not exist in the spiritual world. The living entity is eternal, and he existed before the creation of this material world. Unfortunately he has forgotten his relationship with Krsna. The living entity's forgetfulness is described herein as anadi, which indicates that it has existed since time immemorial. One should understand that due to his desire to enjoy himself in competition with Krsna, the living entity comes into material existence.
