This expansion of awareness cannot but convince people of the truth and beauty of other great religious teachings. Krishna was implying that the quest for spiritual enlightenment must be founded on deep, inner communion, otherwise the result will, sooner or later, be intellectual confusion. For even the simplest spiritual truth is susceptible of misinterpretation, if one tries to understand it by the intellect alone. The basic concern of scripture, therefore, is only secondarily to give careful explanations of the truth. Puzzle-solving is for trudging minds.
True scripture is primarily a call to spiritual action.
It offers practical suggestions for how actually to realize truth. Its primary purpose is to inspire people to desire this lofty achievement. Endless theorizing is for pedestrian minds. More pleasing to God than all the scholarship our brains can hold is to open our hearts to His love. If we love, then even though our brains be completely unlettered, it matters not.
