Our teaching, Kṛṣṇa consciousness, is perfect because we have taken the lesson from Kṛṣṇa. Just try to understand how perfect we are. We don't say anything as "I think," "maybe," "perhaps." No. We never say so. We say definite. Definitive information. Just like we . . . they are speculating Darwin's theory of evolution. We have got perfect knowledge from the śāstras: jalajā nava-lakṣāni sthāvarā lakṣa-viṁśati (Padma Purāṇa). Now, we say there are 900,000 forms of life within the water. We have not gone within the water; neither as biologist we have studied. We have taken the perfect information from the perfect source. We say not one million; 900,000. This is called Vedic knowledge. This is perfect. Jalajā nava-lakṣāni sthāvarā lakṣa-viṁśati.
This evolution theory is already mentioned. Darwin has taken this from this Vedic knowledge, and he has placed the whole thing in his imaginative way. Otherwise the evolutionary process is mentioned in the Vedic scripture. First of all aquatics, then plants and trees, then insect, then birds, then beasts, then human being. Now, in the human being form, because by gradual process of evolution we have got advance consciousness, the, I mean to say, subject matter is given to us. Now make your choice now again. Nature has given this opportunity whether you want to go the sat-patha or asat-patha; whether you are again wish to go to the cycle of evolution or if you want to make further progress. Further progress means this human form of life you can go to the higher planetary system. Ūrdhvaṁ gacchanti sattva-sthāḥ (BG 14.18). Yānti deva-vratā devān (BG 9.25). Now you can make your choice. You are now civilized, very advanced intelligence. Now whether you want to go to the cycle of evolution again or whether you want to stop this and go to your original position.
