The Fall of Purañjana and the Supersoul as the Eternal Friend
Purañjana-Upākhyāna Culmination
तत्र चन्द्रवसा नाम ताम्रपर्णी वटोदका । तत्पुण्यसलिलैर्नित्यमुभयत्रात्मनो मृजन् ॥ ३५ ॥ कन्दाष्टिभिर्मूलफलै: पुष्पपर्णैस्तृणोदकै: । वर्तमान: शनैर्गात्रकर्शनं तप आस्थित: ॥ ३६ ॥
tatra candravasā nāma tāmraparṇī vaṭodakā tat-puṇya-salilair nityam ubhayatrātmano mṛjan
In Kulācala there were rivers named Candravasā, Tāmraparṇī, and Vaṭodakā. King Malayadhvaja regularly bathed in their sacred waters, cleansing himself outwardly and inwardly. Living on bulbs and seeds, roots and fruits, flowers and leaves, grasses and water, he undertook severe austerities until his body became very thin.
We can definitely see that to advance in Kṛṣṇa consciousness one must control his bodily weight. If one becomes too fat, it is to be assumed that he is not advancing spiritually. Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura severely criticized his fat disciples. The idea is that one who intends to advance in Kṛṣṇa consciousness must not eat very much. Devotees used to go to forests, high hills or mountains on pilgrimages, but such severe austerities are not possible in these days. One should instead eat only prasāda and no more than required. According to the Vaiṣṇava calendar, there are many fasts, such as Ekādaśī and the appearance and disappearance days of God and His devotees. All of these are meant to decrease the fat within the body so that one will not sleep more than desired and will not become inactive and lazy. Overindulgence in food will cause a man to sleep more than required. This human form of life is meant for austerity, and austerity means controlling sex, food intake, etc. In this way time can be saved for spiritual activity, and one can purify himself both externally and internally. Thus both body and mind can be cleansed.
This verse describes regular bathing in sacred rivers as a means to cleanse oneself both externally and internally, supporting a life of spiritual discipline.
In the allegory of King Purañjana, such places and rivers illustrate stages of renunciation and purification that prepare the consciousness for higher realization.
Along with any sacred practices, adopt consistent daily purification—clean habits, regulated life, and sincere remembrance of the Lord—to cleanse both body and mind.
