“I hope that you understand what the word ‘spiritual’ really means. It means to search for – to investigate – the true nature of the mind. There’s 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.”
– Lama Yeshe
