PHILOSOPHY OF SOUL
Dandak are also small tracts dealing with the same subjects in brief. Some of you might have gone through these texts; if not, you should do so having taken up one or two stanzas daily for study.
Now let us discuss about the number (of souls); but our concept of number is very narrow like the world of a frog. A frog in a well can hardly conceive the vastness of the ocean and very often such a frog is not prepared to accept such conception of vastness.
By biggest number we mean a million or ten millions. A student of Lilavati Arithmetic, might talk in terms of multimillions, but the numerical values do not stop here. This number is made up of about eighteen digits but the scientists, the writers of sacred scriptures have laid down a number comprising of one ninety four digits, and it is known as Shirsha Prahelika. Jyotish Karandaka, a treatise of Astronomy lays down a number comprising of 250 digits. Moreover we can increase the value of a particular number with rapidity and with brevity by increasing the power of that number by writing a digit overhead the other digit e.g. (9) 2 means 81 but 99 is equal to almost more than 38 crores. To explain (9) means 9 X 9= 81. Now (9)' means (9) 3874 20 489. Now it is very difficult to multiply 9 by so many times as mentioned above the digit nine. Even a prominent professor of mathematics cannot do so. Just imagine what time and means are required to work out this gigantic multiplication. But we can know how many digits would be required for the answer. Every time you multiply 9 with 9 one digit is increasing in the answer, therefore the answer would contain 38 crores, 74 lacs 20 thousand, 4 hundred and 89. We would also like to consider how much time and means are required to arrive at the answer. Suppose a man leaving all his activity, simply writes these digits, then he would require 75 years at the rate of ten digits a minute and he would require a long stripe measuring 611 miles at the rate of ten letters in an inch. Now tell me how to procure this time and means to arrive at the answer of this gigantic multiplication.
But the Arithmetical numbers laid down in the scriptures are more advanced than those described above. The highest possible numbers are designated in terms like Anvasthia, Shalaka. Pratishalaka and Mahashalaka.
Popularly, in practical mathematics Samkhyata (numerable) and Asamkhyata (innumerable) are recognised and here Asamkhya
