Bahir-artha (SB 7.5.31), bahir means external, artha means interest. So those who do not know that the ultimate goal of happiness is Viṣṇu, they think that by adjustment of this external world... Because we have got external and internal. Externally we are this body. Internally we are soul. Everyone can understand that I am not this body, I am soul. I am covered by this body and as soon as I go away from this body, the body has no meaning. It may be a very important soul's body, a great scientist's body, but the body is not the scientist, the soul is the scientist. The body is instrumental. Just like I want to catch something, so the hand is my instrument. Therefore in Sanskrit word, these different parts of the body, limbs, they are called karaṇa. Karaṇa means, karaṇa means action, acting, by which we act, karaṇa. So na te viduḥ svārtha-gatiṁ hi viṣṇum (SB 7.5.31), we are now illusioned under the concept of this body. That is also described in the Śrīmad-Bhāgavatam, yasyātma-buddhiḥ kuṇape tri-dhātuke (SB 10.84.13), ātma-buddhiḥ kuṇape, kuṇape means bag. This is a bag of bones, and muscles, and skin, and blood. Actually when we dissect this body, what do we find? A lump of bone, skin, and blood, intestines, and blood, pus, nothing else.
So kuṇape tri-dhātuke, these things are manufactured by three dhātus, elements, kapha, pitta, vāyu. Kapha mucus, pitta bile, and air. These things manufacturing. These things are going on. After eating, these three things are being manufactured, and if they are in adjustment, parallel, then body is healthy, and if there is more or less, then there is disease. So, according to the Āyur-vedic—that is also Veda-āyur means span of life, and Veda means knowledge. That is called Āyur-veda. So this Vedic knowledge of the span of life is very simple. They don't require pathological laboratory, clinic, no. They require simply to study these three elements, kapha, pitta, vāyu. And they, their science is to feel the pulse. You know, every one of you, that the pulse is moving tick, tick, tick, tick, like this. So they know the science: by feeling the beating of the pulse, they can understand what is the position of these three elements, kapha, pitta, vāyu. And by that position, constellation, they... In the Āyur-veda, śāstra veda, there are, the symptoms, with the... These veins are moving like this, heart is moving like this, beating like this, then the position is this. As soon as they understand the position is this, they verify the symptoms. They enquire from the patient, "Do you feel like this? Do you feel like this?" If he says, "Yes," then it is confirmed. The inner things, how the pulse is beating, and the symptoms are confirmed, then the medicine is ready. Immediately take the medicine. Very simple.
And formerly every brāhmaṇa used to learn these two sciences, Āyur-veda and Jyotir-veda. Jyotir-veda means astronomy..., astrology not astronomy. Because any other, the less than, less intelligent than brāhmaṇas, the kṣatriyas, the vaiśyas, the śūdras, they would need the brāhmaṇas for health and future. Everyone is very inquisitive to learn what is future, what is going to happen next, and everyone is concerned with the health. So brāhmaṇas, they would simply advise about health and the future, so that is their profession and people give them eatables, cloth, so they have nothing to do for working outside. Anyway this is a long story. So this body is a bag of the three elements, yasyātmā-buddhiḥ kuṇape tri-dhātuke (SB 10.84.13).
