What are Maha Vidyas?

Shri Jayesh Pandey asked: What are Maha Vidyas? Could You tell about them? Pardon me for my ignorance. Below Your feet.

Swami replied:- Always try to view the meanings of words in spiritual knowledge with the spectacle made by Sattvam quality, by which you will understand that the ten mahaavidyaas are the powers of the ten senses transformed into practical devotion of God helping your spiritual progress directly or indirectly. You can also understand these ten mahaavidyaas as the knowledge of the nine parts of the creation (Paraa and Aparaa prakruti) along with knowledge of God. If you view the meaning of this word through the spectacle made of Rajas and Tamas, the ten Taamasic work forms of the same power like Kaalii, Taaraa, are seen and your spiritual path gets disturbed. The electricity is one and the same as the basic energy. Its work forms are different based on the nature of the soul. The same electricity is used as light to read spiritual knowledge, which is Sattvam. The same when used to kill the enemy (irrespective of good or bad nature of the enemy) is Rajas. The same is used to kill one self (suicide) and this is Tamas. It is always best to avoid Rajas and Tamas whether it is Pravrutti or Nivrutti.
