“The full recognition of the law of sacrifice, however, lifts man beyond the mental plane – whereon duty is recognized as duty, as “what ought to be done because it is owed” – to that higher plane of Buddhi where all selves are felt as one, and where all activities are poured out for the use of all, and not for the gain of a separated self.
Only on that plane is the law of sacrifice ‘felt’ as a joyful privilege, instead of only recognized intellectually as true and just.
On the buddhic plane man clearly sees that life is one, that it streams out perpetually as the free outpouring of the love of the LOGOS, that life holding itself separate is a poor and a mean thing at best, and an ungrateful one to boot.
There the whole heart rushes upwards to the Logos in one strong surge of love and worship, and gives itself in joyfullest self-surrender to be a channel of His life and love to the world.
To be carrier of His light, a messenger of His compassion, a worker in His realm – that appears as the only life worth living; to hasten human evolution, to serve the Good Law, to lift part of the heavy burden of the world – that seems to be the very gladness of the Lord Himself.”
