Was my client’s older brother in that past life we were shown, the same person now in the current life who caused the chain of events leading to his difficulties with the SEC (U.S. Securities and Exchange Commission)?

This again was impulsed to you and is the case. This person was the former brother, so there is a karmic interconnection that is quite strong and based on many times of discord and intense hatred. This is maintained by resentment and grudges on both ends and will continue until healing is brought to bear. He has awareness within his conscious reach of much of this drama, and it will be fruitful to carry out such a session with him using HMR (Holographic Memory Resolution). A subconscious channeling as well would reach deeper and would get to the primal event. This will allow a full resolution and a change in direction for him energetically that can separate him once and for all from this drama.
