Patanjali himself warns against the Siddhis. It is only if you can go beyond them, if you can reject them, then the higher samadis are open to you. In Advaita Vedanta, this is called Kritopasti and means a person who has completed every stage of Karma Yoga. Sridharam Akrishna had continuous unimpeded vision of his chosen deity for years before realizing that he was Brahman.
