Selfishness limits you. Whenever we classify something like right or wrong, we are just giving our ego a voice. Who decides what is right or wrong? There is nothing wrong in having material things, there is no need to renounce the matter because there is no correlation to spirituality and having or not having — that is just personal preference.
Spirituality is not about having or not having, nor is it about doing or not doing. Spirituality is about expansion. As you go deeper into yourself, detachment from material things will naturally happen. You will find yourself fulfilled without things in a natural way. You will be able to enjoy your luxury car and clothes, yet at the same time, you will have no attachment to them. When you understand the true value of life, you no longer see yourself as a consumer. You no longer care about your title or things – because you are so deeply fulfilled with yourself. Once you reach this point, you will see material simply as expressions of life to be enjoyed. You will also realize that you don’t “have” anything at all.
