Cleanliness is next to godliness. You must take twice bath at least. It is required. And in tropical countries like India, there is no difficulty taking bath three times. Of course, if your body does not permit... But that is Śaucam, to clean. Śaucam. Śaucaṁ bāhyābhyantaram.
- apavitraḥ pavitro vā
- sarvāvasthāṁ gato 'pi vā
- yaḥ smaret puṇḍarīkākṣaṁ
- sa bāhyābhyantaraṁ śuciḥ
The brāhmaṇa is called therefore śuci. He is always clean, taking three times bath, cloth washed, mouth, hands, legs, all clean, with tilaka. That is brāhmaṇa. Śaucam. This is externally. And internally you have to become also śaucam. Bāhyābhyantaram. Bahya mean externally you have to cleanse yourself with water, soap or earth. And internally you have to be cleansed by chanting Hare Kṛṣṇa mahā-mantra. Ceto-darpana-marjanam (CC Antya 20.12). Because if you remain unclean within the heart, simply by washing your external body and cleansing your cloth, that is not complete cleanliness. That may be called hygienic. But real cleanliness is internally and externally.
