Serenity and Contemplation

The highest wisdom comes from two things: serenity and insight.
Develop your serenity, and you strengthen your mind. You are freed from desire.
Develop contemplation, and your strengthen your wisdom. You are freed from ignorance.
Desire and ignorance enslave you! Free yourself with serenity and contemplation.

from Anguttara Nikaya 2s (II, iii, 10)

Loving Kindness

If just for an instant, for the length of a finger snap, you arouse the feeling of loving kindness and develop it, then your are truly a contemplative. You do not meditate in vain. You are truly following the advice of the Buddha. You deserve the kindness given you. How much better if you cultivate that loving kindness!

from Anguttara Nikaya 1s (I, vi, 3-5)
