According to Bhagavad Gita, no one on Earth is free from three Guṇas (tendencies, qualities, attributes) of nature: Rajas (passion), Tamas (darkness or destruction) and Satva (purity).

These gunas deeply affect our state of mind, our moods, nature and our behavior. For example, : A mother who feeds her baby is said to be Satvik; She plays and adores her baby as Rajas and gives her naps generously as Tamas.

The thread on the wrist helps one control mood swings that one experiences time and again in their daily life and gets them into the Satvik state, which is pure and placid



I know now that a studied evasiveness has its own limitations, its own ways of inhibiting certain forms of happiness and pleasure. The pleasure of abiding. The pleasure of insistence, of persistence. The pleasure of obligation, the pleasure of dependency. The pleasures of ordinary devotion. The pleasure of recognizing that one may have to undergo the same realizations, write the same notes in the margin, return to the same themes in one’s work, relearn the same emotional truths, write the same book over and over again—not because one is stupid or obstinate or incapable of change, but because such revisitations constitute a life.
