Many forms of Lakshmi

The word 'Luck' may have been derived from the word Lakshmi - the goddess of wealth :     http://hinduism.about.com/od/hindugoddesses/p/lakshmi.htm

This includes not just money but all kinds of wealth i.e. vidya lakshmi, varada-lakshmi and many other attributes of lakshmi.

Note that the Hindu scriptures talk about 2 different kinds of knowledge:
1) Vidya - everlasting knowledge
2) Kala - knowledge that waxes and wanes (transient) knowledge
Ashta Lakshmi (Sanskrit: अष्टलक्ष्मी,Aṣṭalakṣmī, lit. "eight Lakshmis") are a group of eight secondary manifestations of the goddess Lakshmi, who preside over eight sources of wealth and thus represent the powers of Shri-Lakshmi.
