अहङ्कारस्य दृश्यन्ते जन्म मृत्युश्च नात्मन: ॥ १५ ॥
janma-mṛtyuś ca nātmanaḥ
Lamentation, elation, fear, anger, greed, confusion and hankering, as well as birth and death, are experiences of the false ego and not of the pure soul.
False ego is the pure soul’s illusory identification with the subtle material mind and the gross material body. As a result of this illusory identification, the conditioned soul feels lamentation for things lost, jubilation over things gained, fear of things inauspicious, anger at the frustration of his desires, and greed for sense gratification. And so, bewildered by such false attractions and aversions, the conditioned soul must accept further material bodies, which means he must undergo repeated births and deaths. One who is self-realized knows that all such mundane emotions have nothing to do with the pure soul, whose natural propensity is to engage in the loving service of the Lord.
