Self-love is sadhana(practice) to get back to your true Self. At the moment, your sadhana is based on continual illusion about who you are. The more you feel you are your body, the more mind gets attached to mithya, untruth. In meditation, you feel you are in that blissful state, which is your Soul-state.
Self-love is being conscious you are not fragile body but eternal Spirit Soul. You are bliss!
