(Kadamba Kanana Swami, 19 September 2015, Midrand, Johannesburg, Lecture)
When one corner of the spiritual world becomes covered by a cloud of illusory energy then Krsna cannot be seen, nāhaḿ prakāśaḥ sarvasya, yoga-māyā-samāvṛtaḥ, mūḍho ’yaḿ nābhijānāti, loko mām ajam avyayam (Bhagavad-gita 7.25), Krsna becomes covered by his yogamaya energy.
āvṛtaḿ jñānam etena, jñānino nitya-vairiṇā, kāma-rūpeṇa kaunteya, duṣpūreṇānalena ca (Bhagavad-gita 3.39), Krsna becomes covered when lust is burning in the heart. In this way, the living being resides in this covered portion of the spiritual world. Somehow, due to the illusory energy, living beings are thinking that they are in the material world but Srila Prabhupada pointed out that we are actually in the spiritual world right now. There is nothing separating us from the spiritual world other than our own illusion.
It is not that after a lot of hard work in devotional service, after chanting many, many rounds and after being a very good devotee then may be/possibly/theoretically speaking it could happen that at the end of this life, one might actually go back to Godhead… and it is a long, long journey. No, it is instantaneous.
It is not a physical journey, it is a journey of becoming aware of that other dimension and once that other dimension is there, we are there – it is not like a long drive to the spiritual world…
