Here is what the Buddha said about blessings:
Once the Exalted One was dwelling near Savatthi, at Jeta Grove, in Anathapindika's Park. Now when the night was far spent a certain deva of wondrous beauty lit up the whole Jeta Grove, and coming to the Exalted One saluted him and stood aside. So standing that deva spoke unto the Exalted One in verse:
"Many devas and many men have pondered on blessings,
Longing for goodly things. O tell me Thou the greatest blessing!"
The Lord replied:
"Not to follow after fools, but to follow after the wise:
The worship of the worshipful, - that is the greatest blessing.
To dwell in a pleasant spot, to have done good deeds in former births,
To have set oneself in the right path, - this is the greatest blessing.
Much learning and much science, and a discipline well learned,
Yea, and a pleasant utterance, - this is the greatest blessing.
The support of mother and father, the cherishing of child and wife,
To follow a peaceful livelihood, - this is the greatest blessing.
Giving of alms, the righteous life, to cherish kith and kin,
And to do deeds that bring no blame, - this is the greatest blessing.
To cease and to abstain from sin, to shun intoxicants;
And steadfastness in righteousness, - this is the greatest blessing.
Reverence, humility, content, and gratitude,
To hear the Norm at proper times, - this is the greatest blessing.
Patience, the soft answer, the sight of those controlled,
And pious talk in season due, - this is the greatest blessing.
Restraint, the holy life, discernment of the Ariyan Truths,
Of one's own self to know the Goal, - this is the greatest blessing.
A heart untouched by worldly things, a heart that is not swayed
By sorrow, a heart passionless, secure, - that is the greatest blessing.
Invincible on every side, they who do these things
On every side they go to bliss, - theirs is the greatest blessing."
(from the Sutta-Nipata, vv. 258-69, in F.L. Woodward, "Some Sayings of the Buddha")
