From Pradhana to Mahat Tattva - Characteristics, differences and Transformation

From Bhurijana Prabhu's book Unveiling His Lotus Feet Pages 609 to 620:

What is Pradhana?

• Pradhana is the subtlest form of matter
• Eternal
• Subtle undifferentiated sum total of all material elements
• Saguna Brahman- Brahman with qualities
• From SP purport to 3.26.15
• Brahman mixed with 3 qualities of goodness, passion and ignorance results in material expansion called as saguna Brahmana - consist of 25 material elements including time factor
• Nirguna Brahmana is not mixed with modes, found in spiritual world- unalloyed goodness prevails where nirguna brahmana is found

How does Pradhana become Mahat Tattva?

1. The form of the Lord that interacts indirectly with pradhana is known as Karanodaksayi Vishnu. His glance impregnates pradhana with countless souls all desiring an existence separate from the Lord
2. Pradhana impregnated with the Lord’s potent energy becomes known as mahat tattva
3. The Lord’s Potent energy can be understood as :
1. 3.26.19 – viryah(The Lord’s semen)- His internal Potency
2. Jiva Goswami describes it as conditioned souls
3. Mahavishnu's glance consists of time, the living entities and their karma(Page 352 Unveiling His Lotus Feet) 

Due to the agitation caused by His glance , false ego is produced and manifests in each of the three modes good ness passion and ignorance. Further discussion of how the false ego is manifest and how further transformation happens is discussed in this post:

False ego is the cause of the material creation
