Solitude is the source of happiness

Associate with companions who are in harmony with the Dharma and who don't promote disturbing emotions. Keeping company with unwholesome friends, you cannot possibly avoid being influenced by their evil ways. That is the root of going astray […] Tsogyal, if you want to avoid this way of going astray, cut your ties to superfluous companions and remain in solitude!

Tsogyal, if you want to practice the Dharma in an authentic way, it is most important to cut your ties to unwholesome places, companions, and so forth. So give them up!

Again Master Padma said: Tsogyal, I have told this to everyone, but nobody listens. As soon as the Mara of Death catches hold of you, there is no chance for liberation. Those who do not practice the Dharma will regret this when approaching death. The years, months and days pass by without lingering even a second. This life runs out without pausing for even an hour or a minute, and then we die. The seasons continue, but your life finishes and doesn't wait.

You are not a Dharma practitioner if you don't mingle your mind with the Dharma. (p. 115)

The root of faults is nothing other than your ego-clinging, the attitude of deluded fixation, so cut the ties of ego-clinging! Cast away the fixation on enemy and friend! Forsake worldly concerns! Abandon materialistic pursuits! Engage in nothing but the Dharma from the core of your heart! Just as a seedling doesn't grow on a stone, there will be no enhancement without removing the fault of ego-clinging. You should therefore abandon the root of all evils, ego-clinging. (p. 90)

Don't mistake mere words to be the meaning of the teachings. Mingle the practice with your own being and attain liberation from samsara right now. (p. 100)

The awakened state of enlightenment is your own awareness that is naturally awake. (p. 102)

Fortunate ones, mingle your mind with the Dharma and the happiness of buddhahood will manifest within you! (p. 108)
