tṛṇaṁ karaṁ vidhyati

 The phrase "tṛṇaṁ karaṁ vidhyati" (त्रणं करं विद्यति) can be broken 

down as follows:

1. Tṛṇaṁ (त्रणं) – grass, straw, or a small blade of grass.
2. Karaṁ (करं) – hand or action of the hand.
3. Vidhyati (विद्यति) – exists, is present, or occurs.

Taken together in a literal sense, the phrase translates to:

"A blade of grass exists in the hand" or "Grass is held in the hand."

This expression may appear in classical texts to convey simplicity, ease 

of grasping, or as part of a metaphorical teaching in Sanskrit literature. 

Depending on context, it could symbolize the act of taking possession

of something small and tangible or refer to humility in the presence 

of nature.

Without additional textual context, the most straightforward translation is:

"A blade of grass is in the hand."
