The living entity resides within the body and struggles for existence with the limbs of the body, which are referred to here as citizens and friends. One can struggle alone with many soldiers for some time, but not for all time. The living entity within the body can struggle up to the limit of a hundred years with good luck, but after that it is not possible to prolong the struggle. Thus the living entity submits and falls victim. In this regard, Śrīla Bhaktivinoda Ṭhākura has sung, vṛddha kāla āola saba sukha bhāgala: when one becomes old, it becomes impossible to enjoy material happiness. Generally people think that religion and piety come at the end of life, and at this time one generally becomes meditative and takes to some so-called yogic process to relax in the name of meditation. Meditation, however, is simply a farce for those who have enjoyed life in sense gratification. As described in the Sixth Chapter of Bhagavad-gītā, meditation (dhyāna, dhāraṇā) is a difficult subject matter that one has to learn from his very youth. To meditate, one must restrain himself from all kinds of sense gratification. Unfortunately, meditation has now become a fashion for those who are overly addicted to sensual things. Such meditation is defeated by the struggle for existence. Sometimes such meditative processes pass for transcendental meditation. King Purañjana, the living entity, being thus victimized by the hard struggle for existence, took to transcendental meditation with his friends and relatives.
