Some of us are more bent towards knowledge, some of us are more towards love, and some of us are more towards alertness. But meditation combines all three: love, knowledge and awareness. And, if we catch hold of any one of it and master it, then the other two also come along. If you have digested the knowledge of 'who you are and what this universe is all about', then it is impossible to not be a loving person. You will find that the greatest scientists are great lovers too.
