So manuṣyāṇām, out of the, there are many kinds of men also. Just like kirāta-hūṇāndhra-pulinda-pulkaśā ābhīra-śumbhā yavanāḥ khasādayaḥ (SB 2.4.18). The Africans, the Mongolians, the Huns... There are so many. We know so many types of human beings. Out of that, a few who are known as Aryans, they are the best type of human being. And out of the Aryans, those who are followers of the Vedic principles, they are the best. But those who are following the Vedic principles, they say that "We are Vedic, or followers of the varṇāśrama-dharma"—in common sense they call "Hindu"—but actually, they say so, they do not follow the principles. They do not follow them. They act against the Vedic principles. Therefore it is said that even though one gets this human form of life after many, many millions of years, the living soul, still, there are so many divisions in the human form of life; therefore it is said, manuṣyāṇāṁ sahasreṣu: (BG 7.3) "Out of many millions of human beings," kaścid yatati siddhaye. Siddhaye. Siddhaye means to get the spiritual power, or spiritual rejuvenation. That is called siddhi.
Bhukti-mukti-siddhi. There are three kinds of activities going on in the human society. Some people are karmīs. They enjoy life, or they want to enjoy life by working hard. Enjoyment means āhāra-nidrā-bhaya-maithunam. To eat very nicely and to sleep very nicely, to enjoy sex life very nicely and to make defense force, this is called enjoyment, material enjoyment. If I am secure by defense force and if I have got good bank balance, if I have got a very nice, beautiful wife and if I eat sumptuously to the satisfaction of my tongue, I think I am very much successful. But that is not success. Success is different thing. This is called bhukti, material enjoyment. So bhukti-mukti-siddhi. When one is fed up with this hard working for material enjoyment and get little sense above material enjoyment, gets little sense for spiritual understanding... That we have discussed yesterday. Jñānaṁ te 'haṁ sa-vijñānam (BG 7.2). That is knowledge. To work hard like an ass for sense gratification, that is not siddhi. Siddhi is different thing. Siddhi means to understand the spiritual identification and work for it. That is called siddhi. So the attempt for such thing is called mukti, to get rid of the material entanglement. So bhukti-mukti-siddhi. There are three stages. So siddhi means when one understands his spiritual identity and tries to make his life perfect on that platform, that is called siddhi. Otherwise, bhukti mukti.
So in the Caitanya-caritāmṛta it is said that bhukti-mukti-siddhi-kāmī sakali aśānta. "So long one is on the platform of bhukti, mukti and siddhi, he is restless. He is working because he's desiring." Siddhi is specially meant for the yogis. The yogis, they want to play wonderful magic: aṇimā, laghimā, prāpti-siddhi, īśitā, vaśitā. There are eight kinds of yoga siddhis. That kind of siddhi is not recommended here. Siddhi means to understand one's spiritual identity and work for it; that is called siddhi. So manuṣyāṇām... Who knows it? There is no such education. Therefore Kṛṣṇa says, manuṣyāṇāṁ sahasreṣu (BG 7.3), "Out of million, million persons, one tries for this siddhi, perfection of life, to understand spiritual identity and to work for it." That is called siddhi. And yatatām api siddhānām: (BG 7.3) "One who has attained siddhi and trying for it further, further progress, out of them, millions of such persons, one can understand what is Kṛṣṇa."
