It seems also be a reference to the self-named Swami Satchidananda who provided Alice Coltrane with some guidance and help after the death of her husband.
The title is a play on words referencing the name of the Swami. Alice 'took a journey' in Satchitananda (guided by the Swami) which helped her through the mourning process.
Vishnu Wood, who played on the album (and used to host a jam session we'd go to when I was in college), did an interview with Rolling Stone about it. [1] His guru was (is?) Satchitananda and he introduced her to him.
Satchitananda's Integral Yoga space is still in Manhattan and hosts workshops there (I took one with Laraaji there once).
