In the Gītā He did not say ‘these people, or those people’. ‘Whoever it may be, it is all right,’ Kṛṣṇa said. For this He laid down no distinctions of community or of sex. He did not say who is fit and who is unfit; but for dhyāna on Praṇava He did set out qualifications. Namely: merely remembering the Praṇava, “Om”, is of no use. He said, ‘Keeping all the senses under control and fixing the Manas on God, meditate on Praṇava.’ This is very necessary. When the Manas is wailing this way and that in all manner of ways, one cannot attain the Paramātma merely by saying ‘Om, Om’ with the mouth. For this reason, because one who practises sādhanas of sense-restraint during his lifetime can gain that fitness by that day, the Paramātma said to carry on the search for Satya from birth until death. Instead, could one not begin sādhana only on that day? Why from today, you ask? Surely only one who studies hard all the year can pass the examination at the year's end. If instead, thinking the examinations are a year away after all, one does not pick up a book, does not listen to what the teachers say, does not read what one has written down, and takes up the book only on the day of the examination, the very head itself will be addled. Then how can the examination be passed? Such a state is the learning of an utter sluggard.
