So, the mind is within, the intelligence is within, the soul is within, and outside your body... So this body made of five elements, they are also Kṛṣṇa's energy, and within, the mind, intelligence and the soul, that is also Kṛṣṇa's energy. Two kinds of energies: supreme, er, inferior and superior. Therefore He is outside and inside both. Bahir antaś ca bhūtānām. Every living entity, Kṛṣṇa is existing outside and inside. Therefore we have to purify both outside and inside. That is our human life. Human life means to become purified. Because we are not purified, therefore we have to accept birth, death, old age and disease. This is the problem. Because we are not purified...
That is stated in the Śrīmad-Bhāgavatam, tapo divyaṁ putrakā yena śuddhyet sattvam (SB 5.5.1). Ṛṣabhadeva advised his sons, "My dear sons," tapo divyam, "just undergo austerities." This life, human life is for austerities, penance. Therefore you'll find in the Vedic civilization, big big saintly persons, big, big brāhmaṇas, kṣatriyas, rājarṣis, they are engaged. Just like Lord Buddha. Lord Buddha was the prince, royal family, but still he left everything and underwent meditation to understand himself. There are many others. Bharata Mahārāja, under whose name this country is called Bhāratavarṣa, at the twenty-fourth years of his age, he left his kingdom, his wife, little children, and went for austerity, penance. This is meant for.
This life is meant for not to live extravagantly without any responsibility like cats and dogs. We should be very responsible. Austerity. Little austerity. In the Kali-yuga you cannot undergo severe austerity, but even if you follow little austerity, little something must be done. Little austerity. Just like you do not commit any sinful life. What is that? No illicit sex, no meat-eating, no intoxication, no gambling. This much austerity. If you simply accept these four principles.
Now these Europeans and Americans, they are accepting. You see how they are advancing. You cannot understand the supreme pure, Absolute Truth, keeping yourself impure. It is not possible. You can understand God when you are pure. Yeṣām anta-gataṁ pāpam. It is stated in the Bhagavad-gītā. You cannot understand God if you are sinful.
Na māṁ duṣkṛtino mūḍhāḥ prapadyante narādhamāḥ (BG 7.15). Those who are not purified, sinful acting, sinful, acting only sinfully, such person is called duṣkṛtina. Kṛtina, they are... Kṛti means meritorious. But these rascals are meritorious in doing all sinful activities. Sinful activities also require merit. Even if you become a very expert thief, this stealing is sinful activity, but it requires some brain. It requires some brain. Therefore the word is used, kṛtina. Kṛtina means meritorious. But duṣkṛtina. Their merit is being applied for sinful activity. Similarly, there is another word, sukṛtina. You can employ your merit for pious activities. The merit is the same.
Just like money. Money you can utilize for duṣkṛtina and for sukṛtina. You can utilize your money for drinking wine, illicit sex, meat-eating and gambling. And you can utilize your money for Kṛṣṇa's service, for offering yajñas, for constructing temple, sacrifices, push on the saṅkīrtana movement, Kṛṣṇa consciousness movement. So money is not good or bad. As you utilize it... Similarly, merit, merit also, there. You have got already merit better than the animals, but you have to utilize it for proper service. That is called Kṛṣṇa consciousness. Consciousness we have got, merit we have got. Simply we have to utilize.
Now, here Kṛṣṇa says that bahir antaś ca bhūtānām. You have to undergo austerities to see Kṛṣṇa both outside and inside. If you understand this philosophy, then your life is successful. Antar bahiḥ, antar bahiḥ. Ārādhito yadi haris tapasā tataḥ kim, nārādhito yadi haris tapasā tataḥ kim antar-bahir yadi haris tapasā tataḥ kim, nāntar-bahir yadi haris tapasā tataḥ kim (Nārada-pañcarātra).(?) If you can see Kṛṣṇa, antaḥ, within, and bahiḥ, outside, then your all tapasya finished. You are perfect now. Tapasā tataḥ kim. No more tapasya.
And if you cannot see the Supreme Lord inside and outside, then you may undergo various types of tapasya and education—it is all useless, useless waste of time.
