Why Wool? Insulating the Body's Energy in Meditation

Ask why a meditation cushion is made of wool and silk rather than foam and polyester, and you touch one of the quiet, beautiful details of the yogic tradition. The materials beneath you are not chosen for comfort alone. For centuries, practitioners have sat upon wool and silk for a subtler reason — and the tradition still holds wisdom worth understanding.

The tradition: insulating earth currents

In the yogic teaching, the meditator is advised to sit upon a covering of wool and silk — wool beneath, silk on top — to insulate the body from the subtle downward currents of the earth. Paramahansa Yogananda taught this plainly, instructing devotees to cover the meditation seat (or drape it over a chair) with such a cloth, so that the body’s energy is less drawn toward material perception and freer to rise and settle inward. Whatever one’s view of the subtle, the practice has endured for generations because practitioners found it helped them sit more deeply and still.

Why wool, specifically

Wool is a natural insulator — the same quality that keeps a sheep warm through a mountain winter. Beneath you, it forms a gentle barrier between the body and the floor, both energetically (in the traditional understanding) and quite practically: it keeps the cold of the ground from seeping into the hips and legs through a long sitting. Warmth matters more to stillness than we tend to admit; a cold body fidgets, while a warm one rests. Wool is also resilient and long-lived, holding its loft and shape through years of daily use.

Why silk on top

Silk is placed on the upper surface, against the body. It is smooth, naturally temperature-regulating, and traditionally regarded as a fine conductor for the body’s finer energies. It also lends the seat its quiet luster and beauty — a small dignity for a sacred object. Raw (Dupioni) silk, with its subtle slubs and sheen, is the classic choice.

A seat made to last

There is one more reason these materials endure: they are made to be kept. Natural silk over pure wool, sewn by hand, holds its shape and its quiet through a lifetime of sitting — not a thing to replace each year, but to live with and, one day, to pass on. That is why we make our cushions and blankets, mats, and shawls from silk and wool, in the tradition handed down to us. (Read more on the tradition behind the silk and wool seat.)

Frequently asked questions

Why are meditation cushions made of wool and silk?

The yogic tradition holds that wool and silk insulate the body from the earth’s subtle downward currents, supporting a calmer, more inward meditation. Practically, wool also insulates against the cold floor and lasts for years, while silk is smooth and beautiful against the body.

Does the insulation really make a difference?

Many practitioners feel it does, and the tradition has held for generations. At the very least, the warmth and comfort of wool plainly help the body stay still — and a still body supports a still mind.

Why silk on top and wool on the bottom?

Wool beneath provides the insulation; silk on top is smooth, temperature-regulating, and traditionally regarded as a fine conductor of subtle energy — as well as beautiful.

Is wool and silk worth the cost over synthetic cushions?

For a daily, lifelong practice, many feel it is. Natural materials are warmer, follow the tradition, and — made well — last for many years rather than flattening or wearing out.

Sit warm, sit still, and let the seat beneath you serve the silence.
