The material nature will award you a particular type of body according to your work. So as soon as the body is changed, the whole atmosphere is changed. You are no longer American. You are no longer Indian. You are something else. Therefore your characteristic of rendering service to the nation, that is not permanent. That is temporary, apara. Apara means temporary, inferior.
But because you are soul, spirit soul, part and parcel of God, you have got a particular duty. That is eternal duty. That eternal duty is described here, sa vai puṁsāṁ paro dharmo yato bhaktir adhokṣaje (SB 1.2.6). Adhokṣaja. Adhokṣaja, this Sanskrit word, is applicable to this Absolute Truth. Akṣaja, adhokṣaja. Akṣaja means experimental knowledge, things which you can perceive by your present senses. Just like you can touch. You can understand a thing by touching, if it is hard or soft, liquid or solid. You can smell, you can hear—so many sensual activities. So things which you can perceive by your sensual activities, they are called direct knowledge or knowledge by experiment. But which is beyond your experiment, that is called adhokṣaja. Adhokṣaja means beyond your sense perception.
So God's another name is Adhokṣaja, means beyond our perception. You cannot understand God by directly seeing or by directly smelling or by directly hearing or by directly tasting or touching. It is not possible at the present moment, unless you are spiritually advanced, unless our seeing power is rectified, our hearing power is modified. In this way, when our senses are purified, then we can hear about God, we can see God, we can smell God, we can touch God. That is possible.
