Transcendental Meditation is a superset of all these tools described here for balancing and rebalancing both physical and mental states with an intention to reach higher level of maturity for sustainable enjoyment including both physical or mental one.
TM is just a technique like karezza that progressively provides awareness of balancing and rebalancing all unbalanced states both in physical and mental domain.
These techniques are truly some processes with hierarchy of activities that are mostly excellently pleasing to our senses. The source of these pleasure are in fact issues that keep appearing before us as small or big ones challenging our innovative stretches. innovative sparks are what we experience as pleasing sensation whether it is in sensuous ecstasy or in spiritual enlightenment.
The basic difference that emerges out of my analysis is that Karezza needs two entities to try out an exotic experiences while TM provides the same with you acting as two entities fused into one . This is where searching for courtship partners is well obviated.
