1. Bhakti means to develop attachment towards Krishna, anything relating to Krishna. Bring complete attachment towards Krishna & go back to Godhead & have picnic there with Krishna, eating with Madhumangal or Nityananda prabhu’s nice Chidha-dahi festival. No disease, be always happy & blissful there.
2. Are you completely attached to Krishna and Karshana, things related to Krishna?
If the devotee feels that, "I can be Krishna Conscious without the association of devotees." it is very dangerous situation. More we separate from devotees, more we bounded by the attacks of Maya. The material world is designed to struggle to exist. So, Srila Prabhupada made the situation minimum by having Krishna conscious temples, communities and farm projects, so devotees can live in association with devotees.
In essence, duality means that we forget that we are part and parcel of Krishna. We want to enjoy separately from Him, we want to play the controller.
1. We should not finish our rounds as a duty. Chanting is like a cry of a child for the mother. We should chant in the mood Chaitanya Mahaprabhu gave. We should feel like we are now separated from the lord. How can we feel comfortable? No! The holy name isKrishna. But we are not feeling association of Krishna. This is pity. We should chant in such mood all the time.
2. Chant in the mood as if Lord Krishna, the supreme personality of Godhead, all majestic has just appeared before you.
