How to invoke the Holy Spirit?

The silent voice of the Eternal One constantly whispers, Come up higher, O, my children, and participate in the joys of the Blessed around my Throne of Light! 

Thou Eternal One! whose love

Is everywhere made manifest—

Whose wisdom and whose goodness prove

That, of all friends, Thou art the best—

We thank Thee for each glorious gift,

Which thy Omnific Hand hath given—

That we our prayers to Thee can lift,

The All-Presiding Soul of Heaven.

Father, may we recognise

A Universal Brotherhood—

And feel that Thy all-searching eye

Is on the evil and the good!

May we, like Thee, be full of love,

Be rich in every Christian Grace—

Advancing upward nearer Thee,

Through all the realms of endless space.

We would return our thanks to Thee,

For every blessing we enjoy—

And for the rich assurances

That Thou wilt every sin destroy.

O may Thy Holy Spirit rest

On each dear child assembled here—

And may we feel, Father Blest,

That Thou art ever, ever near!

We thank Thee, Giver of all Good,

That we can visit those below,

And tell them of those radiant skies

Where everlasting pleasures flow—

That we can stamp upon the soul

The impress of Thy boundless love—

And raise it, from its darkened state,

Into the joys of worlds above.

O bless us, Father, with the light

We need to aid our progress on

To those eternal realms of bliss,

Where brighter scenes will on us dawn!

And may we seek to reconcile

Those hearts by hate and discord bound—

Upon our efforts sweetly smile,

That they with vict'ry may be crowned.

We know Thou art our Faithful Friend,

And that Thy love will never end—

If friends prove false—or foes defame,

We know that Thou remain'st the same.

O may we, then, in Thee confide—

In Thee, our Anchor and our Guide—

For Thou, God, in weal or woe,

Wilt prove the truest friend we know!

If darkling clouds eclipse the light

Of Truth's most bright and glorious dawn—

We know, dear Father, that the night

But heralds forth the Coining Morn!

Then, with our hearts baptised anew

In Thy all-permeating love,

May we our heavenly work pursue,

Receiving strength from Thee alone.

We would Thy holy blessing crave

On those dear ones who now have found

The pathway to those lands beyond,

Where Peace and Harmony abound.

Impart to them that strength they need

To aid them in their glorious flight

From world to world, from sphere to sphere,

Upward to Thee, the Source of Light!

May they, O Parent All-Divine,

Exert their powers for others' good—

And labour zealously to bind

All hearts in one Great Brotherhood!

And may the teachings, breathed to them,

To others be imparted, too—

That they may also find the way

To Mansions of the Pure and True!

And now, Father, we implore

Thy Mighty Spirit to descend,

And cause our souls for evermore

In love and unity to blend.

We ask that all (hu)mankind may soon

From discord and from sin be free—

That every soul may bask within

The glorious light of Liberty.

Reposing all our trust in Thee,

We will our pleasant tasks renew,

And strive, in one united whole,

Thy Everlasting Will to do!
