There is a wrong impression that the Hindu spiritual spectrum is dominated by men.
Hinduism, right from the Vedic age has considered women as equals to men.
Scriptures such as Devi Bhagavata have even placed feminine power above masculine power.
Rishika is the feminine gender of Rishi.
The term Rishi has got two meanings:
1. Someone to whom a mantra has been revealed.
2. Someone who is able to see beyond the ordinary world.
By observing intense tapas.
Intense tapas purifies the mind.
In a pure mind, knowledge in the form of mantras arises.
This is different from knowledge acquired through books and learning.
If you look at the Vedic corpus, it becomes clear that all the Rishis and Rishikas have observed tapas.
Along with every Sukta of the Vedas, the name of the Rishi or Rishika to whom it was revealed is also mentioned.
