Those who want to know the truth of the universe should practice the four cardinal virtues.
The first is reverence for all life; this manifests as unconditional love and respect for oneself and all other beings.
The second is natural sincerity; this manifests as honesty, simplicity, and faithfulness.
The third is gentleness; this manifests as kindness, consideration for others, and sensitivity to spiritual truth.
The fourth is supportiveness; this manifests as service to others without expectation of reward.
The four virtues are not an external dogma but a part of your original nature.
When practiced, they give birth to wisdom and evoke the five blessings:
Health, wealth, happiness, longevity, and peace.
