Krishna told Arjuna of a swan, a bright white swan, a hamsa, who in the old
stories stands for the Self that lives inside every person.
"Picture this swan," Krishna said. "She is made of light. She cannot be hurt.
She cannot grow old. She cannot die. By her own nature she belongs to the
open sky, free to fly anywhere she pleases, forever."
Arjuna pictured her: shining, weightless, longing for the wide blue air.
"But the swan has come down to rest upon the earth, to live for a while
inside a body, the way you and I do," said Krishna. "And the earth is the
home of great Nature, who is woven from three fine threads."
"What are the threads like?" Arjuna asked.
"The first thread is white and clear, like a ribbon of morning light," said
Krishna. "That is sattva — calm, happy, full of knowing. The second thread is
red and quick, always tugging, never still, like a restless little fire.
That is rajas — the busy thread, full of wanting and doing. And the third
thread is dark and heavy, like a wet woollen blanket. That is tamas — the
sleepy thread, dull and slow."
"And the swan?" said Arjuna.
"The three threads gently wrap around her feet," Krishna said. "Even the
white thread, even the lovely shining one. One by one they loop and knot, and
soon the swan, who could fly anywhere in all the heavens, sits tied to the
ground, forgetting that she ever had the sky."
Arjuna frowned. "But she is made of light. She cannot be hurt. Why doesn't
she just fly away?"
"That," said Krishna softly, "is the great riddle. The swan is never truly
harmed — not for one moment. The threads cannot change what she is. But while
she forgets herself, while she lets them wrap around her, she feels tied, and
she stays upon the ground, and she cries that she cannot fly."
He looked kindly at Arjuna.
"Every person carries that swan inside — your true, shining, undying Self.
And the three threads of Nature are always near, ready to wind around it. To
understand the threads," he said, "is the first step to slipping free of
them."
