Pratiksha is from the Hindi / Nepalese / Sanskrit प्रतीक्षा (Pratīkṣā — anticipation, waiting, patient expectation). Pratiksha is one of the Hindi + Nepalese feminine names — central to traditional Hindu-Indian + Buddhist Sanskrit virtue-naming heritage. The Sanskrit pratīkṣā concept is central to Hindu philosophical heritage.
Pratiksha does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.

In Pythagorean numerology the letters of Pratiksha reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
