When you become more meditative, the deeper you go into meditation, the more will be your capacity and clarity to understand the scriptures. Scriptures will become witnesses to you that you are on the right track. And when you reach to your innermost core, when you realize your being, then you will know what Jesus means by the kingdom of God, then you will know what Buddha means by nirvana, then you will know what the Upanishads mean by truth — not before that.
