His Holiness Dilgo Khyentse Rinpoche

It is said, “The sign of wisdom is self-control, and the sign of mature spiritual experience is the absence of conflicting emotions.” This means that to the same degree that you become wise and learned, you also become serene, peaceful and subdued – not reckless and busting with pride and arrogance. Year after year, however much your practice progresses, you will be unconcerned about comfort and discomfort, and will have no pride at all. You will always be at peace, untroubled by outer events, with a humble mind, beyond hopes and doubts, and indifferent to the eight worldly concerns – gain and loss, joy and suffering, praise and blame, fame and obscurity. - His Holiness Dilgo Khyentse Rinpoche

There is a saying that goes: “In spiritual practice, difficulty comes at the beginning, in worldly affairs it comes at the end.” This means that, when renouncing ordinary activities and devoting yourself entirely to the practice, you many encounter some outer and inner obstacles; but the more you persevere, the happier you will become. Conversely, worldly activities bring some ephemeral and superficial satisfaction at first; but eventually they result in bitter disappointment. - His Holiness Dilgo Khyentse Rinpoche
