Is having a desire to attain correct spiritual knowledge also due to the grace of God or is it part of one's self-effort?

[An online spiritual discussion was conducted on October 24, 2020, in which several devotees participated. Some of the questions of devotees answered by Swāmi are given below.]

[Reply to a question by Śrī Ganesh] Swāmi replied: Without the grace of God, nothing happens in the spiritual path. But apart from God’s grace, self-effort is also essential. If God’s grace were the only cause for gaining spiritual knowledge, God would have to bless everybody without any partiality. But when God helps a person who puts forth effort, it is not a case of partiality.
