Quick Answer
The 4-7-8 Breath is Andrew Weil's modernization of the classical pranayama lineage from the Yoga Sutras (2.49-2.51). Drawn from Weil's Spontaneous Healing (1995), the long exhale is the part every lineage in this list keeps. Four cycles is the customary round.
Tradition and source
Tradition
Patanjali pranayama lineage (modernised by Andrew Weil)
Classical source
Yoga Sutras 2.49 to 2.51 (Patanjali), pranayama as the fourth limb
Modern source
Andrew Weil, Spontaneous Healing (1995); the ratio has been examined in subsequent breathwork research
What this practice does
Weil developed his 4-7-8 from traditional Indian prāṇāyāma (the ujjayi and nāḍī śodhana ratios) and credits his pranayama teachers without pinning the practice to one named source. The long exhale is the part the sources agree on, and a long exhale is the part every lineage here keeps. The 4-7-8 ratio is one valid pattern; box breathing is another. Same mechanism, different door.
How to practice
The instructions below run 2 to 5 minutes. Read through all the steps before you begin. The practice is not the goal; you are.
The pattern Weil teaches is a short inhale through the nose, a longer hold, then an exhale through the mouth roughly twice the length of the inhale, made with a soft sound.
The tongue tip rests behind the upper front teeth throughout. He begins the sequence with a full exhale rather than an inhale.
The ratio is not the point. In his own framing the relationship between the parts is what carries the practice, and the exhale is the long one.
His instruction is emphatic about stopping. This is a practice to leave early rather than to extend.

Crystal companion
In Crystal Cassandra's work, certain stones are the somatic companion to certain practices. The pairing is not magical; it is a steady weight in the palm that becomes part of the noticing.
Lepidolite
Lepidolite is the stone most commonly held during storm-weather practice in modern Western crystal healing. It is a lithium-bearing mica, a fact of geology that has nothing to do with why the tradition reaches for it. What recommends it here is plain and physical: it is soft, flat and pleasant to hold. Many practitioners simply keep it in the hand for the length of the practice.
