So the Kṛṣṇa consciousness movement is very scientific, authorized. Try to understand Kṛṣṇa. We have got so many literature. Don't waste a single moment. Kālena. And Cāṇakya Paṇḍita, the moral instructor . . . he's not spiritual instructor, but moral in . . . but he has said that āyuṣaḥ kṣaṇa eko 'pi na labhyaḥ svarṇa-koṭibhiḥ. One moment of your life, if it is wasted without any profit, just imagine how much loss you have suffered. Because you cannot get back one moment of your life again even if you are prepared to pay millions of dollars. That you cannot get back. Nineteen seventy-four, 19th January, passed—you cannot get it back again. If you . . . any rich man comes forward, "Please get me back again 1974, 19th January," "No, sir, that is not possible." Any price you offer, it is not possible. So just imagine, if we waste our time, how much loss we are suffering. We calculate loss and gain. So don't waste time.
Kāla, kāla is very . . . yoga system means to save time. The whole process, mechanical process, of yoga, mystic power, means to save time. We have got a limited duration of life. Suppose one is destined to live for . . . utmost they will live, anyone, but nobody goes to live for hundred years—say, seventy, eighty, sixty or something like that. Gradually it is reducing, and it will reduce twenty to thirty years. That will be duration of life, because people are becoming more and more sinful. So that is fixed up. A body is given to us by the superior power, and the duration of life is also fixed up. Even the greatest scientist, he cannot increase a moment's time for his life. That is not possible. A moment's life. Professor Einstein was a great scientist, but he could not find out any means that instead of living for, say, eighty years, he could live eighty years, one day. No, that is not possible. That is not possible. Your destiny, duration of life—fixed up. And how it is fixed up? The machine is breathing. Machine is breathing. Just like the clock goes on, tick-tick, tick-tick, tick-tick. As soon as the tick-tick stops, then whole thing is lost. Similarly, our breathing is going on, tick-tick, tick-tick, tick-tick, a fixed time. Just like you wind your clock, so that winding will help, tick-tick, for a certain duration of time, say, twenty-four hours. Similarly, there is winding in our life, a spring. That "tick-tick" means this breathing. So if you . . . breathing exercise means if you can stop breathing, then you increase your life. That is called samādhi. No more breathing. That is Vedic, I mean to say, yogic success. Stop breathing. There are yogīs, perfect . . . not these gymnastic-wālā, no. Real yogīs. They can remain without breathing for days together. That means the days he does not breathe, so much time saved: he increases his life. Suppose daily if he stops breathing for three hours, that means daily he saves three hours time. So in hundred years about . . . so many, so much time. So in this way, the yogī can live for three hundred years, four hundred years, six hundred years. Still there are yogīs. This is called yogic success.
So kāla, to control . . . you cannot control time. Just like if you have got one hundred dollars, if you deposit in a bank, you will get some interest, but you cannot make without any endeavor two hundred dollars. No, that is not possible. But if you don't spend it, then the hundred dollar remains. Similarly, your duration of life is there, and it is being wasted by breathing. If you can control the breathing process, then your life can be increased. This is yogic . . . but after all, we are under the full control of time. Kālena sarvatra gabhīra-raṁhasā. That is explained here. Kālena vā te balināṁ balīyasā. Very, very strong. There is no power . . . your so-called scientific power . . . you cannot struggle against the influence of time. So save time. Save time.
Another process is, save time, if you chant Hare Kṛṣṇa mantra then the time is not lost. Time is not lost. Hare Kṛṣṇa mantra, read book, Kṛṣṇa Book. Any moment, any time you spend for thinking of Kṛṣṇa, working for Kṛṣṇa, chanting for Kṛṣṇa, eating for Kṛṣṇa, dancing for Kṛṣṇa, that time is saved. That time is saved. Therefore it is recommended, harer nāma harer nāma harer nāmaiva kevalam, kalau nāsty eva nāsty eva . . . (CC Adi 17.21). Otherwise, by yoga practice, it is not . . . how many men can actually practice yoga? It is all farce. This is possible. Even a child can take part, Hare Kṛṣṇa mantra.
