Harisaranardhi answering to questions from Devotees - Day 17 May 2020

Questions for the day -
1) is there any connection between dwaita and Advaita siddhantha?
2) As a working person, should we offer our prayers in the pooja room or temple always but instead think about him and pray him in mind whenever I have time? Is it wrong?
3) Why did Ravana kidnap Sita in spite of being such a learned Siva Bhaktha? Is it because of his poorva karma phala?
4) Is Dharma an individualistic perception? Can my Dharma be the same as yours? If different, how to know my Dharma? Is Dharma situational? Is Dharma applicable only to individuals?
5) All the poorams have been cancelled? Is it bad omen or a new beginning?
