Kabbalah zu Tehillim 85:14

You will ask: How with the man who makes a journey, and, away from his wife, ceases to be “male and female”? Such a one, before starting, and while he still is “male and female,” must pray to God, to draw unto himself the Presence of his Master. After he has prayed and offered thanksgiving, and when the Presence is resting on him, then he may go, for by virtue of his union with the Presence he is now male and female in the country, just as he was male and female in the town, for it is written: “Righteousness {zedek, feminine of zaddik} shall go before him and shall make his footsteps a way” {Ps. 85:14}.
