LIC Policy requires clarification?

Dear Friends,

LIC “Proposal for Insurance on Own Life” Form or application was sent to me. What is the purpose of it? What are its advantages and disadvantages of this policy?

Actually I want to enroll into LIC – Marriage Endowment Or Educational Annuity Plan. Can i enroll online? What are the advantages and disadvantages of this policy? Is there any application or Form Available so that i can download?

Please suggest.

Regards
