Why embrace materialistic pop psychology masquerading as spirituality, when you already have a treasury of wisdom in your inheritance?
Perhaps it has been obscured by the actual behaviour of those who claim to walk the path, but that wisdom remains nonetheless.
The tradition your grandparents were on teaches you how to deal with the major spiritual diseases which affect us all.
Our task is not to inflate our false ego, but to conquer it. A true path of self-development will not teach you to be selfish, but to find purpose in service.
Don’t embrace a product designed only to make its creators rich. Follow those that ask no fee. Seek and you will find.
