height, 8Y in length and 6Y in diameter. The corresponding description is given in Table 5. It is clear that this can not be based on PY. Basing it on UY also, looks like an exaggeration. Not only this, 108 Jambū trees of half the dimension of the main tree are surrounding it. If we assume that there is at least one tree surrounding it in one direction, there will be a row of approximately 27 trees of 60 km length covering a distance of 27 x 60 = 1620 km. in one direction. This is equal to a distance from Delhi to Kazipeth, Bombay, Veraval and Howrah. It seems that more than half of the present India will contain only the family of Jambū trees. This description seems to be imaginary when one thinks the current distances and description of the trees.
The Jambū island has a diameter of 105 Py23. This island has the Bharata Khanda with an area of 1/190 of main island and a diameter of app. 526 PY. The island has mount Meru 24 in the center with is 99, 000 PY overland and 1000 PY underland. The current values for these details given in Table 5, suggest that it is very difficult to determine the category of reliability about them. Table 5 gives the values on the basis of UY = 15 kms. and PY as 500 UY. Calculations based on other values of UY also yield similar discrepant values. These values can only be presently explained on the basis of faith in canons and religion which do not seem to require verfication. Time and its Units : Smaller Units
Time is also one of the Jainistic realities assisting in the continuity and changes in the substances. There is some discussion whether it was originally included in the realities or added later. But it has come to stay. It consists of two varieties — ideal and apparent or de jure and de facto. The apparent time is countable and is useful for us. The ideal time is eternal and causes continuity. The substantiality of time has been discussed by many philosophers of east and west. Scientists call it as a frame of reference to measure present, past and future course of events as every change is related
