External / Marginal / Internal

Although Krishna is invisible to us in our present state, we can perceive His presence through His energies, which are everywhere. Although innumerable, His energies fall into three primary categories.

1) ANTARANGA SAKTI - Internal Potency (Yoga-maya)

2) BAHIRANGA SAKTI - External Energy (Maha-maya) (Bg. 7.4)

3) TATASTHA SAKTI - Marginal Potency (Living Entities) (Bg. 7.5; 15.7)
Krsna is the saktimana or the source of all energy. (Bg. 7.6)

Marginal Energy - We finite spirit souls are expansions of Krishna's marginal energy. We can choose to live in

1. the spiritual world or illuminated by spirit
2. the material world - deluded by matter  

Both the external energy (matter) and the marginal energy (we souls) can become fully spiritualized by contact with the internal energy through acts of devotion to Krishna (Bhakti-yoga).
