Love is not an emotion. It is your very existence.
By self-study, by observing, by being hollow and empty, you become a channel - you become a part of the Divine. You are able to feel the presence of Divinity. All the different angels and devas, all these different forms of our consciousness, start blossoming.
While fasting detoxifies the body, silence purifies speech and brings rest to the chattering mind, and meditation takes you deep into your own being.
