The essential teachings of the Buddha

Yo sàro so thassati.” “Whatever is the heartwood will stand firm.” or “Whatever is the true heartwood will endure.” (MN. Sutta N. 29)
“Yo paticcasamuppadam passati, so dhammam passati; Yo dhammam passati, so paticcasamuppadam passati
“Whoever
sees Dependent Origination (paticcasamuppada) sees the Dhamma; whoever sees the Dhamma sees Dependent Origination.[M.I. 28, 191] 
Sabbadānaṃ dhammadānaṃ jināti.”
The gift of Dharma surpasses all other gifts, the giving of Dhamma surpasses all other giving, and of all gifts, the act of giving the True Dharma is the most noble and worthy of respect.
Yo vo ānanda mayā dhammo ca vinayo ca
desito paññatto so vo mam’ accayena satthā. Vinayo nāmabuddhasāsanassa āyu Vinaye țhite sāsanam thitam hoti.”
O dear Ānanda, after I, the Buddha, pass away, my Dharma and Precepts—skillfully taught, practiced, and applied in daily life—will be your true teachers. The virtuous Precepts are the very life of Buddhism. When you practice the virtuous Precepts and Dharma of the Tathāgata faithfully and diligently, the Triple Gem will endure and shine for all beings across the world.

Poem version

O dear Ānanda, when I, the Buddha, have passed away,
My Dharma and Precepts—taught with care, lived each day—
Shall be your teachers, guiding you in every peaceful step.
The virtuous Precepts are the very life of Buddhism;
Practice them faithfully and diligently,
And the Triple Gem will endure, shining for all beings.”
When doing good, speaking good, and thinking good things, you will certainly obtain the five precious blessings: 1. Blessings of wisdom, 2. Blessings of long life, 3. Blessings of good health, 4. Blessings of wealth, and 5. Blessings of beauty.

In Buddhism, wisdom, virtue, and concentrative meditation are the three fundamental practices of core education for everyone.
