"spiritual"
"I hope you understand what the word 'spiritual' really means. It means to search for, to investigate, the true nature of the mind. There is nothing spiritual outside. My rosary isn't spiritual; my robes aren't spiritual. Spiritual means the mind, and spiritual people are those who seek its nature. Through this, they come to understand the effects of their behavior, the actions of their body, speech and mind. If you don't understand the karmic results of what you think and do, there's no other way to become a spiritual person. Just knowing some religious philosophy isn't enough to make you spiritual."
__Lama Yeshe
