They are also totally dependent on man for all their needs. Moreover, Bhairav Singh describes Man, as "Kamina" and "Harami" in his language. This tells about the traditional notion of man being more dominant and powerful than women in India. This also speaks about the patriarchal society and the female subjugation which is still prevalent in the twenty first century India. But this concept of male domination is challenged through the character of Jaggu, who, after being rejected by her father, lives independently in a rented flat in Delhi. She is independent in all aspects of her life. It is she who ultimately encourages PK to expose Tapasvi Maharaj and the various religious hypocrisies associated with him and his religious sect. It is the same Jaggu who helps PK in getting back his spaceship remote and enables him to return to his home planet.
Friendship is a major constituent element of the two extreme societies that we witness in the film. The friendship between Bhairav Singh and PK is of great importance. It is Bhairav Singh who extends his hands of friendship until his death in a terrorist bomb blast in a Delhi railway station. It is Bhairav Singh who unknowingly helps PK learn the language of Bhojpuri through a prostitute. In contrast to this friendship we also have television reporter friend of PK in the metropolitan setup who helps PK regain his lost spaceship remote. The bondage portrayed in these two kinds of friendship described here is apparently different due to their cultural background, but at the same time are very similar. Both help PK in their distinct ways to get his lost property, the spaceship remote, with which he returns back to his home planet. The universal quality of friendship which surpasses all boundaries are very finely depicted in the movie.
The theme of universal love is projected through the love of PK towards Jaggu (Jagat Janani Sahni), and also through the love of Jaggu and Sarfaraz, a Pakistani Muslim.
