AC Bhaktivedanta Swami Prabhupada

Woman Interviewer: What are other major beliefs besides love, understanding of Kṛṣṇa, understanding of oneself, which you would like to impart to me?

“Prabhupāda: Love is the basic principle of Kṛṣṇa consciousness, and love is the basic principle of all our activities. So love is there, dormant, but that love is not being properly utilized. So Kṛṣṇa consciousness is the movement to revive that original love and the original person with whom that loving transaction can be executed.”

The trancendental technical science is as follows,  Srila Bhaktivinod Thakur outlined everything..

Thākura Bhaktivinoda in his Bhajana-rahasya describes four types of anarthas and four categories within each type, that hold up the flow of trancendental love .
The four types of anarthas are:
1) tattva-vibhrama – illusion about spiritual knowledge 2) hṛdaya-daurbalya – weakness of heart
3) aparādha – offences
4) asat-tṛṣṇa – material desires

Illusion about spiritual knowledge is of four types:
1) sva-tattva bhrama – illusion about one’s original posi-
tion as a taṭasthā-jīva
2) para-tattva bhrama – illusion about the Supreme Lord
3) sādhya-sādhana bhrama – illusion about the processes of sādhana and prema-bhakti
4) virodhi-viṣaya bhrama – illusion regarding subjects
unfavourable to Kṛṣṇa consciousness

Weakness of heart is of four types:
1) tucchāsakti – attachment to objects not related to Kṛṣṇa 2) kuṭināṭī – deceitfulness
3) mātsaryam – enviousness
4) pratiṣṭha – desire for fame

Offences are of four types:
1) kṛṣṇa-svarūpa-aparādha – offences to the form of the Lord
2) nāma-aparādha – offences to the Holy Name of the Lord
3) kṛṣṇa-tadīya-aparādha – offences to the devotees 4) jīva-aparādha – offences to other living entities

Material desires are of four types:
1) aihikeṣvaiṣana – desire for material objects 2) para-trikeṣu – desire for heavenly comforts 3) bhūti-vāñcha – desire for mystic powers
4) mumukṣa – desire for liberation
